Pros: The place is located in a great part of Montreal. The house is walking distance to a couple of great grocery stores, some lovely bakeries, good restaurants and a SAQ. We usually say in the old Port, but we were happy we chose this neighbourhood. The house was spotless and there were lot of thoughtful touches (for example, the kitchen was fully stocked with everything you'd need to cook). The parking is right in front of the house which was really great and there is a park right across the street. The wifi is quite fast! We also really enjoyed the heated floors in the bathrooms. Check-in was super easy (there is a lock box, so you don't need to try to arrange to meet Jean).
Cons: The noise - there are some bars close by and you can hear music playing at night. Although, I should note, that it's actually quiet in the day and the music doesn't start till 10 or 11pm. We stayed over the weekend, so it might not have the same sound issues on the weekday. If you're a light sleeper, it can be annoying but once we put in some ear plugs we were fine. We also recognize it's right in the city, so there is bound to be some noise. The bed in the upstairs room is not super comfortable (we ended moving to the another bedroom). The couch has definitely seen better days but was perfectly comfortable to sit on.
All this to say, it was a really nice place to stay - it's got a lot of room and it's in a great location. Just bring some ear plugs and you'll be fine!
