First I just want to say we LOVED Henry's place. It was perfect for the five of us staying there. The location is perfect in a wonderful quiet uncrowded brownstone-like neighborhood with even ritzier places a block over. Staying here gives you the feel of living in Montreal. We took advantage of the 80 bus (stop a block away) to take us downtown, to the river, to the airport (with one change), and to the Metro. A 3-day pass (which isn't 72hrs FYI) is the easiest way to get around (covers all buses and the metro).
The communication with Henry and our warm arrival (OMG, fresh bread!!) couldn't have been better. The place is perfect with a light and bright seating area with doors that can be opened into the courtyard, a well-equipped kitchen, AC, and comfortable beds. This is a place you wouldn't mind living in for awhile. There are lots of restaurants close by including Lemeac if you want French, the number one bagel place in all of Montreal, St Vieteur Bagel shop, and a place we wished we had visited (Milo, greek food). Henry can give you many more suggestions. Henry provides lots of helpful information for visitors, even OPUS cards to borrow. Overall we had a perfect stay and certainly would return!
