I had a great experience both in Montreal being my first time and the first time using AirBnB! I was running extremely late on my arrival time and Alex-Maria were extremely understanding.. The only bump I experienced was when I got there the door was locked but that was quickly resolved.
Alex-Maria made my wife and I feel at home as they even left out some cake that was kosher knowing that we were there for a Jewish event, and that little touch of kindness is what would make me go back anytime I visit Montreal.
