I stayed at Tammy's place with my husband for almost 3 months. We were in touch with a friend of Tammy, Benji, who was very welcoming and helpful. The apartment is comfortable and full of light, there is plenty of space and it is divided into a huge living room + kitchen space, 1 bed room, and a huge bathroom with brand new shower and bathtub. A plus for us (Italian) was the bidet :)
The apartment was fully equipped with nice furniture, kitchen supplies, etc. The location is also another plus, in the Plateau and close to the city center. Buses and metros are available walking distance. The neighborhood itself is very lively, full of restaurants, cafes, shops, etc.
If we come back to Montreal we would definitely stay there again.
