I had a mostly disappointing stay at this hotel, the biggest problem being the air quality. The hotel reeked of cigarette smoke in just about all areas except the breakfast dining area. At night, cigarette smoke bellowed from the air vents and the windows cannot be opened, and given the climate of Shenzhen, not having air circulation at night is not really an option. Most areas of the hotel post smoking prohibited signs, but the local Chinese patrons smoke anyways and the biggest problem is that the hotel management is indifferent, despite complaints by me and my colleague of other patrons smoking in adjacent rooms on nonsmoking floors, with doors wide open. The hotel clearly only aims to cater to a local clientele, where smoking indoors is generally accepted or tolerated. Hilarious, the hotel places ashtrays below the no smoking signs posted beside the elevators, and these ashtrays are almost always filled with cigarette butts.
