I've stayed at The Coli many times over the years. It's always first class but at mid price. It's one of the best hotels with easy access to east side of DongGuan. (See LongGang TangLa and TangXia SanJen/Gem) My one complaint: there's a westerner-style bar/lounge--good! --but the service is terrible. The iPad menu is stupidity. I once waited forty minutes for a gin & tonic. (Which turned out to be a glass of warm gin. The staff almost exploded when I went behind the bar and made my own.) Yes, this is China so I don't expect a perfect cocktail or a bar. Five stars for the Coli

It may be located a while from downtown Shenzhen, but it was a pleasure to stay at the Coli hotel. Staff in the lobby were friendly and helpful, there was a big selection of food for breakfast (including some awesome pastries), and everything from the lobby to the rooms to the conference rooms was immaculate.
