I was a member for a month recently.
I greatly enjoyed hot yoga classes from Nicolas and Kimiko.
Karate classes were also fun.
Very clean.
Really nice and knowledgeable instructors.
Friendly and Eco-friendly
I just wish it was cheaper and easier to get to.
If you bike, bixi station is right next to the studio.
Had dozen yoga teachers in past, Nicolas is the one in a million kind yoga teacher. During corpse position (the last relaxation pose), I often notice that he gently massages students' shoulders. He is so caring, and the class is so profound. (more about him here http://www.nicolasadeline.com/ )
