Our group of 14 adults stayed here during our week trip to Montreal. It was around a 40 minute commute (by bus and then train) to downtown Montreal which we didn't mind. The area is nice too with some convenience stores and places to eat down the street, as well as a park that some of us had fun at.
When we arrived, check in was easy and the place was clean. We didn't realize how loud we were being, which was the only major issue we had with the place. Before coming to stay here I had agreed with the host that we would not be too loud but I guess we underestimated how much the neighbours can hear. With this big of a group of friends we tend to be loud during our conversations because of laughter and talking over each other, and ended up getting a few noise complaints from the neighbours. We ended up trying to be quiet for the rest of our stay and couldn't really all be in the same room together which was kind of disappointing, but we struggled to keep the noise level down when we were all together. Another point about noise is that we can hear footsteps and moving furniture from the upstairs apartments and I believe some of us were disturbed during sleep.
The condo was nice and clean when we arrived. During our stay we noticed a few bugs here and there but nothing we couldn't handle.
Overall, I believe this place was a good deal. However, I believe next time I come to Montreal I'd probably look for a place a bit closer to downtown if I intend on sightseeing. And if I come with a big group again, probably a place where we are able to be loud.
