Great location within walking distance of McGill, Concordia, museums, Mount Royal, the subway, and lively restaurants and businesses of all sorts. If you're looking for that downtown-Montreal feeling, this place is for you! Decor is minimal to nonexistent, and there is really no living room as such (the largest bedroom sort of doubles as one, but it's still essentially a bedroom), but the apartment is clean and the beds are comfortable. The host was responsive and helpful.
One caution: This is a terrific address if you don't have a car. if you do, be prepared to find a lot or garage and pay for storage (the hosts recommend one), or to do a lot of moving your car from one spot to another (and maybe walking a considerable distance to find those spots).
