I used the small room in the back to create and practice a dance routine. The room isn't sound proof so you can definitely hear the classes and music next door, but that was completely smoothed over by the hospitality by the teachers! They checked on us every half hour to make sure we were okay, complimentary bottles of water (we were working hard!), and they opened the back door for us so we could have circulating air.
Very generous, very professional, and a very lively atmosphere and group of people!
