The space was very clean and well decorated, especially the bathroom. One of the few spots near the city with parking on site. Also, since its a converted coach house, the exterior of the building is very beautiful, and It's tucked into a backyard so it's very private.
From what I can tell every single major road in Montreal is under construction right now (obviously at no fault of the AirBnB). I would recommend taking the subway from Vendome station if you're going downtown or to the old port, it's relatively quick on the orange line. Vendome station is a ~10 minute walk from the AirBnB. It takes a bit of time to get to the Mount Royal neighborhood on the subway because you have to transfer to the green line. However, the Mount Royal neighborhood has the best restaurants IMO, especially this place called Bagels Etc. There are some really good restaurants right near the AirBnB. Try cosmos snack bar across the street, get a Creation sandwich.
Also just a general travel note, me and my girlfriend can only speak english and spanish, and we never had an issue communicating with anyone in Montreal. Every service worker at a museum or restaurant you interact with is most likely bilingual. We only talked to a few locals, but most of them seemed to know English too. Road signs and subway signs are all in french, but it's usually pretty obvious what they mean.
