I stayed here with my family and the 6 of us were very with it. The place was very clean, minimalistically decorated, nice and cozy. The kitchen had enough supplies and we were able to do some grocery shopping and eat in as well.
Location was very convenient with lots of restaurants and local coffee shops around. The only note I would add is that if you're planning on renting a car while staying here, make sure to ask for parking because parking on the street is not very easy (you need a permit for most areas and the spots that don't require a permit were always full).
I would definitely recommend this place and would stay here again when traveling to Montreal.
