After entering this place, you must leave your shoes at the door and go downstairs to a steam room where you are not allowed to get out for the entire 90 mins of the session.
I've been there for over a year and every class are fully packed to the edges.
However, I have been to cleaner places, and would really help if they had a water filter fountain to top up hydration needs.
They have a 10 day unlimited yoga for $20 which is a fantastic introductory price.
