Centre Luna Yoga is one of the nicest yoga studios I have been to in Montreal. The space is small but very cozy and has a great atmosphere. I know others have posted the same thing here on Yelp but Bram is also my favourite teacher.
The great things about Centre Luna is Bram and the very nice China Gel that put on you. It helps your breathing if you normally have a stuffy nose like me and it feels very relaxing. I also like that Bram tells us stories and tales at the beginning of each class and sets the mood for the class.
The only con I can think of is that you have to bring your own mat each. They will charge you for rentals.
I don't know if I can afford to attend much longer but I certainly enjoyed my time there.
