The air conditioner only can be used in the summer time. The Hotel switched off their central system for air conditioner on Oct. 13, 2019. But the hotel didn't inform this matter to their guests first. The staffs said that they couldn't help to improve and solve this problem. The only thing you can do is to choose to open the window of your room. However, the hotel is located on the main street. The noisy crowd, cars, buses...etc. always disturb and wake you up. If you book this Hotel, you must be careful about this point.
