First off - I would say this place is NOT a great for beginners, as I'm convinced they would feel overwhelmed by the studio practice to have it's instructors not ask if anyone is new at the beginning of the classes. Fortunately, I had been doing Yoga for a while before this and so I already was familiar with a lot of the moves so I was able to keep up with the pace.
I was thinking of getting a friend to sign up with me for one of their Groupon deals, but I was glad I did not as she would have likely quit after the first class. As others have mentioned the instructors give very little instructions and just expects the class to know the routine as if it were an intermediate level class.
As for the studio itself, it is indeed cramped with 30+ people for each class. This studio attracts a lot of young professionals, which I found great as my other yoga experiences were with a room full of gray haired people and old men with a a lot of body hair. So seeing younger healthy bodies sharing the floor was a plus!
For the men, the change room is quite spacious considering the ratio of men:women. It has multiple showers and double sinks and enough room to not have accidentally rub butts against each other.
So overall, I would say it`s a decent studio. They have a variety of classes and lots of good after work time slots every day of the week. It's good for those who already know some yoga, but not for newbies that are sucked in by Groupon type deals.
