Charles' location is quite convenient - it is in a quiet neighborhood but close enough to some of the major neighborhoods to walk or a 15min cab ride. Although we enjoyed your stay in Montreal, it could've been better. Depending on your living style, this place may not meet your expectations.
Although advertised as renovated and beautiful, I would disagree. The wall paint is peeling along the ceiling corners and corners were dusty with webcobs. Not ugly, just not as we were expecting.
The bed is also not very uncomfortable. It dips really deep in the middle quite a bit. Felt like a very old, used bed.
There is no door between the living area and bedroom, and the washroom door doesn't lock well in case privacy is top priority. Didn't bother us too much but a couple of times the neighbours' going in and out woke me up because of the thin walls.
