I bought a 10 class pass a while ago through a Groupon deal. I've been to a few yoga studios in this city and what really makes Imprint stand out is the small classes and attentive, knowledgable, and friendly instructors. Furthermore, the instructors have very calm voices and don't talk too much. I've been to a few classes at other studios and the instructors keep talking while you're trying to do balance poses and I find it incredibly distracting. At imprint I always leave their yoga classes feeling rejuvenated. The pilates class was great too, I loved the focus on not straining the lower back and maintaining your 'imprint'.
In terms of the atmosphere, it's pretty no frills and there's no showers that I'm aware of. The studio isn't really big but it perfectly fits about 8 people (which is a full class size). I like this more than studios with 30 people in a class and the instructor never gets to see if you're doing anything wrong. My only gripe would be that the changeroom doors face the reception desk so if someone opens the door then people outside can see right in.
