We had a great stay at Driss's place (2 families, 10 people). The location is fantastic, with the bustle and activity of pedestrian-friendly Mont Royal down the street. Metro (grocery store) was a 2 minute walk. Lots of great restaurants nearby. We had 2 cars and parking overnight was a bit of an issue - it wasn't too difficult to find street parking but with restrictions, you had to move your car in the morning. We ended up parking at a lot about 10 minute walk away. There are Bixi bikeshare bikes closeby - highly recommend getting a bike and doing a ride around Montreal (super bike-friendly streets).
The apartment itself was very clean, family-friendly and the kitchen was well stocked. Wi-fi was solid. The dining area is in the foyer so it was a bit tight with the table/chairs. Toiletries, towels, sheets were all provided and very clean. The weather was hot during our stay so we had to have the window AC units on the whole time - it takes a bit of getting used to the noise but it drowns out the street sounds. The bedrooms all have blackout shades, which is a thoughtful touch. Driss was very responsive and check-in/check-out was super easy. Highly recommended.
