The room was not well ventilated and full of cigarette smell. The carpet was also very dirty and tatty. I complained the staffs and asked them to move my room. Couldn't enter the replacement room at the first attempt because of keycard issue, had go back down from the 22nd floor to the lobby at the 10th floor. The new room had better smell and better carpet. However, I found other problem, the water drain was blocked and the aircond was not cold enough. Too many problem with this hotel, definitelly will not stay at this hotel again.
