I can't compare this to any other yoga studio as it's my first one.
What I do know is: the studio is new, very clean, good ventilation and my 5:30AM Instructors are great. They really make a point to help correct your postures, and give you the little extra push you need!
The 5:30AM class is not crowded at all. Sometimes the later morning and afternoon classes feel like your shoulder to shoulder.
