I stayed in the apartment for three months during my internship at UdeM. It really is good value for the money, everything is furnished quite stylish, the kitchen is well equipped. The location is excellent, so many bus stations nearby that take you anywhere. The metrostation Laurier is also just a short walk. Also a lot of cute small shops and Cafés and Parcs very close by.
It was never noisy in the night and I really enjoyed my stay overall - it became a home away from home. Also if there was a problem Sylvain would always be very helpful! Would highly recommend staying here and I would definitely come back if I'm in Montréal again!
Only tiny negative aspect if you come by car is the parking situation, there are not a lot of free spaces to park, just to keep that in mind!
