The checking in/out with the lockbox was very easy to use. The room, bathroom and the kitchen was very clean and tidy. They also provided maps and brochures in the room to give you ideas of where to go in Montreal. The place is near some restaurants, a Wal-Mart and metro stations. It's a really good place to stay.
Although, I never got to meet the hosts, Chris and Marc; you can communicate with them via the airbnb app. They are quick to respond with anything you need.
