Great location and very spacious. Great value too, especially during the winter months. Almost perfect walkability score, pretty much everything from grocery stores and night clubs to restaurants and museums are within a 10 minute walk. Host is very responsive and helpful.
There was some construction work on both sides of the building, but the noise was minor and manageable. We stayed during a time when the whole city of Montreal was essentially renovating, so it's understandable. Some music would permeate up from the shisha bar downstairs after midnight on Fridays and Saturdays, but it's not too disruptive. Also do note that there's a couple flights of stairs up to the apartment with no elevator.
All in all, I would highly recommend to couples visiting and work-from-home tourists.
