We stayed there for 2 nights and we had a great experience. (Strongly recommend it)
The apartment was super clean. Even if you want to stay more than a couple of weeks, this apartment has all the amenities that you need. 2 bedrooms with 3 beds. Each bed has its own tv + a tv in the living room.
The unit is very quiet although the neighborhood is lively and nice.
It takes you 35 min walking to Old Montreal (or 10 min with subway).
Last but not least, Remi and Marie are very kind and a great host.
