The appartment itself is fine. It doesn't face onto the street, and the street is quiet anyway. Very convenient for shops, metro, Bixi bike (and ideal location for me personally as I was spending most of my time at the Universite de Montreal).
The appartment is not well insulated from noise from the neighbours, so could be an issue, but I had no problems (sounded like the neighbours upstairs spent about 20 mins every evening putting up a complicated sofa bed or something, which was very audible).
Communicating with Ihor was extremely quick and easy
