This place is practically the best thing ever.
It's my first time at yoga (and hot yoga) so I have nothing to compare it too, but I'm pretty sure it's one of the best yoga studios in Montreal. I swear they have everything there, free lockers, showers, filtered water fountains, they let you rent towels and mats, and they sell smoothies (which I swore to myself that I would try one day). The moment you enter the studio, you don't even feel like you're in downtown Montreal, it's as if you've been magically transported to a hot temple. And for the classes, well they're simply amazing. The teacher was completely professional and really helpful.
If you're going there, get ready to be sweating!
