We were visiting Montreal for family (of four) vacation and stayed at Magali's place. It is very spacious, with lots of room to spread out and a well-equipped kitchen, washer/dryer and cool bathroom. There is a front balcony with table and chairs, as well as a terrace out back with a table, chairs and a number of green plants and herbs (which Magali graciously offered if we needed herbs for cooking).
The apartment is neighbors with a dépanneur (the Québécois term for a convenience/corner store), which is handy for pop, candy or other small items. In summer, the street has a leafy Parisian residential atmosphere, where people stroll or bicycle by and neighbors stop to have a chat with one another.
At the end of the street (corner of Jarry and Boyer) is a Dairy Queen that is popular with people in the neighborhood. A little farther, but still within easy walking distance, is an IGA grocery store that has a great selection.
The apartment is a close walk to the Metro (subway); Jarry station is only about a ten minute walk. All along Rue Jarry are shops, restaurants, cafes and bars. It is a very good base for visiting all of Montreal, since the Metro is extensive and so is the bus network. Also, the Jean Talon market and Little Italy neighborhood are within easy walking distance.
I recommend staying at Magali's place and enjoying all that Montreal has to offer!
