The Plateau is the best location in Montreal. The metro, a bike, or a good walk gets you to all the sites of summer in Montreal - the Jazz Fest, Jardin Botanique, Marche Jean-Talon, and the mountain are all accessible. Great selection of restos all along Mont-Royal or Laurier and you don't have to deal with the high prices of the tourist traps in Old Town.
The home is surprisingly light and modern. Would definitely stay here again on our next visit.
