The air conditioning is controlled centrally. They decide when you need it and when you don't. Even in sweltering weather, they turn on the air conditioning at ~7:00 pm and turn it off anywhere between 3:00-6:00 am (I am writing this at 8:30 am from inside the hotel and the a/c has been off for a few hours; my inside room temperature is already 23 centigrade and the sun is only just coming up). In other words, there is NO AIR CONDITIONING on during the daytime, when the temperatures are well above 30 centigrade. When I complained, I was told that guests are out touring during the daytime and no guest has ever complained about not having air conditioning during the daytime.
I'm packing up today and moving to another hotel. I regret moving otherwise, as the service is good. Everything is basic and otherwise okay. However, it is deceptive and cruel to turn off the air conditioning and make the room you are paying for uninhabitable during the daytime.
