Checked in room 321, the aircond is not cold and the bathroom is dirty. There is no internal lock, which means anyone can go in with a hotel access card. We cannot sleep at night as the air from the aircond is not cold, and we requested a room change. The staff were helpful and changed us to room 221, which is much better. The hotel is practicing energy saving, e.g., the corridor is dark and minimal lights are opened. Then they will only give 1 access card so that the air cond cannot open when you are out. If you have other choices, please don't select this hotel.
