The apartment is all that is promised on Airbnb. We felt right at home and it was enough space to accommodate four people without getting in eachother's way. (up to eight could be accommodated)
The location is very good as it is right at the centre of a lively neighbourhood and all of Montreal's destinations are easily reached by public transport or -in our case- walking.
The communication with our hosts was very easy - they were very responsive and professional, yet friendly, in arranging all the details (a full manual on all things concerning the apartment was provided).
Overall we can definitely recommend this apartment!
