We stayed at Julien's apartment in Old Montreal for 4 nights over the New Years holiday and could not have been happier with our stay. The apartment itself is very clean and is in an incredible location; it's very central and easy to walk to many locations in Old Montreal and close to a subway stop so that you can get around to the other neighborhoods.
Julien was a great host - he was very responsible, offered local tips, and was extremely flexible with getting the us the keys when we arrived on a very late flight. Would love to stay at this apartment again!
