I had a wonderful stay at Martin's condo with two friends (and plenty of room for more). He left thorough directions on how to access the keys and, since we arrived late, we were happy that we didn't have to inconvenience him! We felt right at home and the location was great - we walked to Mile End (15 min) and used Uber to get around at night. There's a cafe right downstairs too. Try Restaurant L'avenue (two blocks away) for breakfast and Le Chien Fumant for dinner (10 min walking). Would love to stay here if I'm in Montreal again!
