The keys were not in the lockbox at the time of check in, but the hosts responded quickly to our call and someone came to deliver the keys to us right away. Communication with T&E was fantastic - they sent daily messages to us asking if we needed anything.
It is worthwhile noting that the apartment building is really old and the halls smell like tobacco (the room itself did not smell). We were thankful that the elevator was working as the stairs are really steep and narrow. One of the windows in the living room had a huge crack in it and some doors were really difficult to close.
True to the name of the Airbnb posting, it is an "impeccably furnished" space. The location is convenient and everything is within walking distance. The airbnb is very clean and spotless. Netflix on the TV, beautiful views from the window and strong air conditioning in the bedroom were amazing touches. I would recommend T&E's place if you want somewhere convenient and comfortable to stay in Montreal.
