Does the hotel have air conditioning at all? How hot were the rooms in summer?
No AC, at least not in my room on the 5th floor. But they supplied one of those tower fans that was very effective. Personally I'm not a big fan of AC always end up with a blocked nose. The weather was really hot when I was there but I found the room perfectly comfortable. But if you like that 'stepping into the fridge' feeling, then the answer's definitely no!
