There is no AC in the studio but there are two fans that you can use. The ceiling fan seemed to just push around warm air but they were excellent for airing out the room. There is a musty smell once you enter the room -especially if it's been closed up for the day. Michael and Cristina were very kind to provide, tea, bathroom soaps and shampoos, soy sauce, and ear plugs. We should have used them while our neighbors were having a great time. The walls are fairly thin so you can hear everything including the child running around upstairs. If you're in need of a place just to sleep,l and you're a semi heavy sleeper, you'll like it. :)
