The service staff in this hotel is amazing HOWEVER, the aircon in the room is terrible. I had no good sleep for a week when I stayed. U totally feel no aircon in the room whether it is 16 degree or 5 degree celcius. I d complaint 3 times already but it makes no difference. Its either the hotel thats trying to have everything kept at high temperature, no wind/air flow from aircon or the maintenance team has bad English.
