Yoga + Music + Amazing Instructors = Wanderlust
This is hands down my favourite yoga studio in Montreal. Having tried a series of different places ranging from trendy to snooty, to hippie and even to down right strange, Wanderlust just seems to get it right.
They teach a variety of yoga styles, so whatever your preference you'll likely find it here. There are also lots of schedule options, including a daily affordable class for $5.
Eric, one of the owners and instructors, is very welcoming as are all of the instructors and staff. The friendly vibe means you'll typically get greeted by name when you walk in.
Each instructors sets their own music based on personal preference. You can expect to hear some indie, folk, electronic, etc. I didn't realize how enjoyable yoga could be with music until I tried it.
