First of all it is first negative feedback I post in my life. I was tempted by good reviews, flexible check-in ( Key safe ), I had an appointment in Budapest while coming back to home country. The apartment itself was matching the description and the pictures, however before my arrival someone must had a really great night in this apartment... and that was not cleaned by the Personel of the O3 Hostel. In the apartment there were personal items left by previous guest ( like hat, some tobacco ? I am not sure ). In the various places in the apartment there were female bunches of hair. And most importantly in the bed lining there were dry white stains ( I do not want to imagine what was that ) and also more female hair... The glass handrail on the entresol that were a lot of handprints. Also the floor near bed was covered with red stains, maybe after some wine ? The same color stains were visible on the both bedside tables. The bathroom itself also did not looked like it was cleaned. There were no any towels, even to wipe hands. After contacting with Airbnb support and sharing the pictures of the room and bed lining without saying a word they made a refund for me. I did not decide to stay at this place. I am really disappointed, place had got many good reviews, and it was the most expensive apartment by O3 Hostel. Unfortunately due to this situation I had to cancel appointment and try to solve out the situation, for this no one is going to pay me. The apartament definitely have very big potential, but at first they need to work on the cleanness, for now I totally do not recommend to stay at this place.

Very bad experience. The entrance of the place is dark and blocked by big trash bins which smells badly. The apartment is on the 3rd floor and there is no elevator in the building which was not mentioned anywhere until after i made the booking. Had to carry all my luggages up and down 3 floors. The checkout time is 10 in the morning, lol so weird. Dont fall for the low price, its not worth it. Book yourself a hotel instead.

Fantastic, comfortable and affordable stay. Right next to St Stephens bascillica and walking distance from Jewish quarter street food and night district. Surprisingly cheap for the quality of room, but has a shared kitchen and bathroom. Will definitely stay again when in Budapest!

Cut back on the yelling at their guests and put a proper shower curtain in the bathrooms and make sure the television is working.

No problems with the room itself as it was clean and simple other than that we had to put the duvet cover on the duvets ourself as no bedding was on the bed. The shared toilet was clean enough whenever we used it so no issues there. Although this most likely isn't an issue the owners can solve, I did find that the stairs were very unsafe and the light wasn't working meaning we had to use a flashlight to get up and down the stairs I'm the evening.

Wonderful room. But very scary stairs. Close to Nyugati train station.

Fantastic place. All new, super clean and comfortable, very Convenient location within 5 min walk from the bazilika. Com Mon area has a couple of tables and looks all very chic. Looking forward to stay here again!

Very clean and nice. Great position in city, everything important is very close.

The room looked nice, I can give the hotel that. Service was OK. Location 10/10. However, there was hair in my bed, one of the charging sockets did not work properly, the heating was poor, (we had to sleep with jackets on), and the shower was switching from cold to warm and then freezing cold water. The staircase is very creepy and especially at night. I think the rooms have potential though, should be looked into a bit more.

Verry good and clean room also value is great!
