We stayed here during the heat wave in NYC and while this place does not have central AC (a rarity in NYC), we were able to stay cool with the bedroom unit and AC in the kitchen. I recommend closing the bedroom door to stay cool at night. The only thing that was a little different was having to turn on the hot water switch. I didn't read instructions the first shower and had a cold one... that was my own fault. We also left the switch on and had to deal with a cold shower that way. Something to keep in mind!
