To put it simply, this is the best stay I experienced with Airbnb since I started to use this service 3 years ago.
Jacques was very welcoming, organised and helpful. He took the initiative few days before our arrival to make sure all details were clear for our arrival. Once there, everything we needed to know about the house was clearly described in a booklet he prepared (french and english available). Even the restaurants recommended around the house are their.
The house is simply fantastic. Very cosy, kitchen very well equipped (so you can enjoy a worry free holiday cooking) a fantastic little garden to enjoy the sun. The location we found was very good. Less than 10 min walk to Jean-Talon metro station and 15min walk from the famous Jean-Talon market (highly recommended to get your local fresh food supplies).
Parking is easy in the street, but be aware of parking regulations to avoid getting a ticket. We unfortunately didn't pay attention on the first day we parked after landing in Montreal (tired from the journey) and got a ticket for parking too near a fire hydrant. The good news is that it is just a 2 min walk to the nearest bank to pay it (but I don't recommend this experience :o)).
