I'm not sure about the past reviews all I can speak from is my personal experience at this studio which has been great. I bought the deal for 20 classes too and have been to about 5 of them so far with no problems. The instructor (I think her name was Christine) was great... shes helpful and goes at a steady pace. I love that this place is simple... not all about the amenities.. Im going for a good yoga class and that's what I get. They always leave a fresh bowl of fruit for each class as they leave which is a nice little touch. I always leave the place feeling great which is all I can ask for.
