Although this place is a higher end hostel and not what I had expected as I chose AIRBNB, the organization of the host is very good and he was very attentive to my needs.
If you need a QUIET place to sleep, this is not the place for you unless you bring earplugs. The set up for the AC makes the rooms completely soundproof less welcoming every sound from the outside into your room. I had mine changed to the uppper floor at my convenience and it didn't change the noise levels. The area is the busiest in Montreal (great if you are there on vacation for fun) and people do hangout and make noise until late in the surroundings.
Since this a hostel, the bathroom situation was less than pleasant but at least I never had to wait at all to use it; and what he calls a common area is just a sofa and a microwave.
