A gem of a place, more of less within the McGill campus grounds, and accessible to all of central Montreal. It's a very tiny studio apartment, but space is used very creatively, with a comfortable bunk bed over a hide-a-bed. It is very charmingly appointed by Stephanie the propriator.
I would recommend it for any single traveler, or a couple that doesn't have huge space requirements. It has a well appointed kitchen and towels and soap are generously provided. It's also shockingly quiet for a downtown space, like a country cottage.
