I stayed 4 nights this time. For the first night, the air conditioning is malfunction so that the room temperature is cold (20.5 degree C) for the whole night even I set it to 26.0 degree C on the air conditioning control panel. The panel can show the setting value of 26.0 degree C but the setting value does not work.
Next morning, I went 1st floor and told service counter about this. They sent a technician / service guy to my room. He checked my setting showing 26.0 degree C so he said the air conditioning can be set to 26.0 degree C and it is OK. If you feel cold, just turn the air conditioning off...
Oh..., I know the control panel can be set to 26.0 degree C but the real room temperature shows 20.5 degree C and I feel the room temperature is very cold. This room has glass window but it cannot be opened so that I think I cannot turn the air conditioning off...
Later, I went to 1st floor and asked the service counter to change to another room for the remaining 3 nights. The service counter helped me well and the air conditioning of the new room is OK if I set it to 26.0 degree C.
My experience is summarized as follows:
The room (8th floor) for the 1st night: Terrible
The room (10th floor) for the 2nd ~ 4th nights: Excellent
Technician / service guy: Terrible
Service counter: Excellent
