We stayed here with a large group of 11 guys and we all had more than enough space. The house is really clean and well maintained and has everything you would need to keep busy (pool table, foosball, Xbox, TV, chess, and poker set).
The house also has a great back covered deck which was great for hanging out outside or playing poker with the whole group. Like others have said there is a highway in the back and the neighborhood is far from the city (20 min Uber ride) but the ride isn't bad and you can't hear the highway at all as it is elevated (and we spent a lot of time outside on the back deck).
I would highly recommend this house for anyone looking to visit the beautiful city of Montreal. This was my first time using AirBnB and could not have asked for a nicer and better host than Evgeny. He was quick to answer all questions (and I had a lot).
Thank you again for a great stay Evgeny!
