Hotel management refuses to take responsibility for putting public safety at risk. I commute by bike every day and my route takes me by the front of this hotel in the afternoon. There is a protected bike lane that is separated from the street by stanchions and is clearly painted and marked. Unfortunately the entrance and exit to the AC Hotel valet stand goes right through it. Making this worse, the valet staff would regularly park cars in the bike lane causing me and other cyclists to have to leave the protected bike lane and merge with traffc. In late September, I was fed up with this and stopped to talk to the hotel about it. I've worked in the industry in the past and I know that if you really want something done, talk to the general manager. This wasn't just a simple problem, this was the hotel staff and valet putting public safety at risk due to laziness and a lack of empathy. After a significant wait, the first person to come talk to me was a woman who identified herself as the Front Desk Manager. She was clearly very annoyed at having to talk to me at all, this was evident in her posture, her tone of voice, and her choice of words. I asked her why she was annoyed and she attempted to excuse it as taking my issue very seriously. This was a lie as she quickly tried to absolve the hotel of responsibility because the valet is a contractor. I reminded her that the valet represents the hotel, regardless of who they are paid by. She asked for my business card, which I don't have, and I asked for hers which she said she would get for me. Soon the valet supervisor arrived who was very pleasant to talk to and said he understood the problem and would try to "be better". Putting public safety at risk is a big deal and I advised him that being better isn't good enough, they need to not block the bike lane. The front desk manager told me I was dealing with the valet now and walked away. I asked for her card and she repeated that I was dealing with the valet now. I contacted the local enforcement and the hotel was issued a warning. Thankfully, I haven't seen this problem again since, but I have a feeling that it's only a matter of time. I contacted corporate about the rudeness and annoyance of the front desk manager and they promised someone would contact me in 5 to 7 business days. I'm happy that this seems to have been resolved, but not at all impressed by the crassness and cowardliness of the hotel front desk manager and the refusal of the hotel to contact me to discuss this issue. If this is how the hotel treats a public safety risk that they created, I would hate to see how they treat paying customers. I'll choose a chain other than Marriott next time I travel.

Service was outstanding. Lianne was amazing. Great service and very helpful. Food was great!!! Hotel staff was great. They handled it all had great service from the time we walked in till the time we walked out. We will be back soon great location for anything and everything downtown Denver. Thank you, Andy Fisher

Hotel itself is clean and conveniently located downtown. Rooms are small without some amenities that you'd expect from a higher-end hotel. Our bed was terribly uncomfortable with rock hard pillows. My biggest complaint was the breakfast that NO ONE mentioned was not included with our room rate. We did not order any additional hot meals, just had a simple pick of yogurt, fruit, toast and coffee and spent $45 for 2 people. How continental breakfast is not included after spending $500 for 2 mediocre nights is beyond me. Very disappointed and will not be returning. I've had better experiences at La Quinta!

Always love staying here. Pillows would be the only item that I feel could be greatly updated. Bar staff up top was great but you hit a home run with Sau at breakfast. Great server, extremely nice and attentive as well as welcoming. Really is a great part of your team and clearly loves his job and being around people!

Rooms were super small. They over designed the room so everything would fit in a compact size. Didn't like that I was brushing my teeth and looking directly at my bed. The writing desk was super small. There was no where near enough space to places suitcases comfortably. Their over proclaimed "restaurant" for breakfast was nothing special and to me overpriced for what you get. Both check in and check out we're not expeditious. Both took time with staff that did not have enough training. Hotel was "ok" at best.

What a great stay! Great modern rooms with fantastic views, cozy lobby perfect to meet with business partners or friends. Loved the Corrine restaurant on the other side (sister hotel connected to AC), and gorgeous rooftop on 20th floor for drinks and views. Friendly service from every single person including welcome and check in emails from a GM. Will be back!

My stay was amazing, you are within walking distance to everyting! There plenty of restaurants within walking distance, the bar on the roof top has the best views in the city. But, the best part of this hotel was the GM who went above and beyond for my stay, as well as the bartender at the lobby bar. Can't wait to come back!

The room is rather small but that's not the problem. There are no drawers or even a place to lay out your suitcase. There's no closet, just a pole to hang your clothes by the door. The workspace is simply a small shelf, barely big enough to fit a laptop. The bed and shower are great. Not a good room if you need to work for business. I also don't like the fact there's no place to put my socks and underwear. No microwave either by the way. The tiny thing that I think is a coffee maker is just strange, not sure how to use it. The restaurant is amazing and a great rooftop bar. Great service. Just a block from the convention center. But the room is a big disappointment.

The staff at the hotel couldn't have been more pleasant, highlighted by the attentiveness of the housekeeping staff. We were never left wanting and can't say enough about their positive attitudes in a profession where, I'm sure, it is not always that easy to do. Congrats on having a terrific property!

The hotel was clean and the hostesses were great. Arne was exceptionally kind and thoughtful! She really made our experience great and excited come back and explore more here in Denver.

The check in was good. The front desk agent was really nice and even found me a bigger room. The place was clean and had a nice vibe to it. The location, being downtown right next to Mall Street, was great. The reason I gave the service 3 stars was because I used the Marriott app and requested a toothbrush kit and never received it, even though it said it was delivered and there was no agent after dark, so I just went without. Overall, it was a nice place with pretty decent rooms.

This AC is a great hotel. Yes, the rooms are a bit small and there isn't a lot of storage, but people complaining about this aren't familiar with AC properties. The lobby is modern with a pool table, several bars, and a restaurant. The breakfast is great and not too expensive. Rooms are clean, modern, and have good views. The TVs are smart/internet TV capable which is great. The windows have a great curtain/shade system that is very easy to use. Hotel Parking is unfortunately overpriced at around $50 per day Valet - I found a nearby garage that charged $13 for 24 hours about 2 blocks away at the mall.

All of the employees I encountered were wonderful. The location is very close to the convention center. The food and beverage options were very good and the lobby bartenders were outstanding. The hotel was very clean and nicely kept. Would definitely stay there again.

This is our first time staying at this Marriott hotel in Downtown Denver and we love it! The hotel has a boutique feel to it, the rooms are cozy and well appointed! The health club is very nice, the restaurants are very good 👍 and the staff is excellent! We will definitely return!

My best friend and I stayed at the AC Hotel for 2 nights and were very satisfied with our stay. One of our favorite aspects of the stay was the breakdown buffet. For $21 it was well worth it. The food was fresh and the selection of breakfast items was fantastic. We thoroughly enjoy it and would highly recommend it. Our server, Sau, was welcoming, attentive, and friendly. You could tell that he genuinely wanted each guest to enjoy their breakfast. Thank you Sau!

I'll definitely come back to the AC Hotel. My check in was very welcoming and the front desk staff was very attentive and kind. My room was perfect with a great view. The rooftop bar is also a great spot.

First time staying at this hotel. Very great experience and was reasonably priced for this time of year. Staff were very friendly. Plenty of restaurants well within walking distance. My room had a great city view. Had breakfast a couple of times at the AC Kitchen. It’s a buffet style but can order hot items upon request. Sau was very attentive and provided excellent service. Visited the hotels rooftop bar, “54thirty.” Plenty of heaters for the cooler nights. Very unique drink and food menu. Definitely, haven’t seen a lot of those items at other Marriott properties. All very tasty and wasn’t disappointed! I saw they had an old fashioned that sounded unique called “Crystal Clear Old Fashioned.” Had to order to try and will say it was the best old fashioned I’ve ever had. The General Manager came over and spoke to me about the drink and how it came to be. Also, how thought and effort went into the entire menu along with this unique drink. Very much appreciated learning the back history of it all. The gym is also on the top floor and very large. Has multiple cable machines, aerobic machines, and dumbbells. Also over looks the city with a great view. Will definitely stay at this hotel again in the future. Anyone staying in the are for business or pleasure should give this hotel a try. Will not be disappointed.

Outstanding! We celebrated my birthday at 54Thirty and the drinks and food were incredible. Not to mention… the views! The best party was the team. David and the crew were communicative, courteous and so accommodating. There was even a reserved table for my friends which was a lovely surprise! We felt so welcome and taken care of. Thanks to everyone at 54Thirty - highly recommended and can’t wait to visit again!

It's a nice hotel and the location is good but it's really geared toward a solo business traveler. The rooms are on the small side and there is minimal storage if you wanted to unpack. No place to store a suit case except maybe a single carry on size. Housekeeping was spotty at best. 4 night stay and on day 3 they forget to replace all the towels, asked at the front desk, said someone would be right up, never came. Day 4 apparently our room was 'somehow skipped" for service. The most important advice I can give if you are considering staying here ... DO NOT STAY ON THE 20th FLOOR ESPECIALLY ROOMS 2001 - 2009. I was in room 2002 and at the end of the hallway is the entrance to the rooftop bar and the gym. The door starts opening and slamming between 5am and 6am with the gym crowd, continues all day and then picks up again into the evening with the bar crowd. Not sure what kind of design puts guest rooms next to high traffic public spaces.

It was a very wonderful place to stay. From the amazing view from the rooftop to the top notch quality of the Corinne restaurant. The staff did an outstanding job all the way. I was there for five days and enjoyed every minutes.

Hotel was nice. Great room. Customer service was poor. I was charged twice for things such as valet parking when I didn’t have a car at the hotel and also a room charge. Management couldn’t even explain why. They didn’t bother to compensate me for my inconvenience. Watch your card details when dealing with this hotel.

Right in the heart of downtown and walking distance to many of the attractions. My room was clean and had everything I needed; the hotel has a great rooftop deck and a restaurant next door. Staff was courteous and accommodating, Sau, in particular was very helpful in the breakfast bar area. Would recommend this hotel to anyone staying in Denver.

My wife and I enjoy staying at new (to us) hotels in Denver. We often do quick weekend trips a few times a year. This past weekend we stayed at AC Hotel in Denver, which was amazing. The room we had had amazing views of Downtown Denver. Yes, the room was a slightly smaller size, but it was just the two of us and it was just fine. We really loved the vibe of the hotel. The AC Bar on the main level was a great place to sit with a drink and hang out for a bit. We also got to enjoy the rooftop bar which I do think is technically part of the other hotel that shares the same building. But the rooftop bar was a really cool place to hang out. Although the second night we were there, the host/staff was pretty rude and because of that, we left immediately. AC Hotel is in a great spot to be able to get to great places in Denver. All in all, we for sure will be staying at this hotel again in the future. It was both of our favorite hotel we have stayed at so far.

From valet to check in the staff were professional, friendly, and helpful. The hotel was great and it was in a good location as we were going to an event and it was within walking distance so very convenient. The valet is expensive but we were short on time so it was convenient. The bar tender was great we were able to order a quick bite and a drink. The drinks were well made - very good, he gave us directions to our event, very helpful. Overall stay was great will return

Spent 3 nights at this hotel for a conference at the convention center. Location is great for the convention center as well as walking around the city. Service was excellent from check in to check out. Rooms are modern and very clean. Housekeeping was done very well. Complimentary coffee in the mornings before my day began was helpful. I didn’t have to run out to get a coffee. Thank you for a very comfortable stay.

The hotel is drastically understaffed and the staff they do have is not well-trained. I've gone round and round with their front desk, accounting department, and director of rooms yet my hotel bill has yet to be corrected. I have filled out countless versions of the same forms over and over again. This is absurd. Also, their valet was quite slow to respond and rather chaotic when they finally did. Do not recommend this hotel at all. There are plenty of other Marriott branded hotels in Denver with much better service.

I stayed here in Oct of 2020 and completely forgot to leave a review. This hotel is in my top 3 for sure. Absolutely loved the rooms, the staff, the amenities and the atmosphere. Covid did restrict housekeeping from entering rooms and there were no microwaves or fridge in the room at the time but no big deal for me. Everyone was so helpful, sweet and just made our stay overall a memorable one. I’m not an easy person to please when it comes to rooms and hotels tbh. I feel most are overpriced and they under deliver but I just can’t understand why this is only considered a 3-star hotel. Love it here and I would definitely recommend to family and friends.

Comfortable, clean hotel centrally located. Fun roof deck bar. Corner room was very spacious. Late-night food is not easy to come by in this neighborhood though, so if you’re craving a 1am pizza after a night of drinking, you’re gonna be out of luck.

This place was 1000% amazing. The bar, the pool table, the snacks, the restaurant, the staff. The rooftop bar!!! OUR ROOM!!! My wife and I felt like we were back on our honeymoon in Paris and Prague with how well these hotel rooms were designed. Amazing, and an equally amazing price point too.

I was recently in town for a conference and this hotel was the perfect location. Most hotels in a city can be loud, but thankful this place was very quiet. The rooms are modern and clean. Definitely one of the best Marriott properties!

With tickets to History Colorado and Comedy Works, we needed a convenient hotel for our mini vacation. There are a lot of hotels in this part of downtown Denver and we were thrilled with our choice of AC Hotels on 15th and California. The staff were delightful, particularly the bartender who dispensed lots of local information with our drinks. The room was stylish and efficient, with a great floor-to-ceiling view of California Street heading through the most vertical part of Denver. The blustery walk to Comedy Works and back was thankfully short. The subsequent walk from our room to the rooftop lounge was all of 10 seconds long. Even on a cold January night, we were perfectly comfortable thanks to the radiant heaters and warm blanket. And I have a new appreciation for the blue bear peeking into the Convention Center directly below. I rarely score a 10 when reviewing hotels; there is always something that could be improved. In this case, I can't think of a single thing.

For the price per night I was disappointed in several aspects of the hotel. We stayed at the AC Hotel during a winter freeze, and poor sealing around the window caused frost buildup in our room and prevented us from being able to warm up our room how we wanted. We were also disappointed to discover that despite the cost per night of the hotel, there was no on-site parking, pool, or a refrigerator in the room. The hotel is not clear on where to park upon check-in, and instead pushes guests to have their cars valeted, at a cost of about $53 a night. For our two night stay in Denver it cost an additional $107 for parking. While the location of the hotel is excellent, there are other hotels in the immediate vicinity that offer stays for the same price and include the on-site parking, pool, etc. I would not stay here again and would instead stay in a different hotel should I desire to stay in downtown Denver again.

I am writing this because of the general manager. He emailed me before I even checked in to see if I had requests for the room being an elite member of Marriott. I have never gotten this email from any Marriott manager before. I was quite impressed. I had asked him some questions and was very helpful and insightful on his answers. I have stayed all over the world with Marriott and this manager was the first to ever email me like this. I would highly recommend him and his team!
