i was in toronto a while ago and bought a groupon for quad east. unfortunately, it was a busy trip and i was only able to use two of the five classes - but compared to the prices at the studio i belong to in vancouver, i still got a super good deal.
the space itself is amazing. it's clean, the change rooms/shower area are spacious and bright. the staff are super nice and helpful. both classes i attended were great - challenging, for sure, but that's what i was there for.
the only reasons i'm not giving 5 stars: i feel like shoe rental should be included (i've never paid for this before) and also i kind of thought derek was a bit of a dick - good class, though :)
