This review is for this listing (https://abnb.me/Lezz9Baysqb), as Christina let me know when I arrived that the room I had booked was no longer available due to her son unexpectedly needing it. But it all worked out -- I ended up in a bigger room (though sharing a bathroom with 2 people, not 1) and still had a great stay!
The location is excellent -- easy access to 2 metro lines (green and orange), easy to get to/from the airport on the 747, and very easy to get around on foot as well. Christina provides everything you need, including some toiletries. The best part for me is that she was flexible with check-in/checkout times, so I was able to maximize my time in Montreal! Would recommend this place to others.
