Olga’s place is perfect for the budget traveler. You will have a spacious room, comfortable bed, clean and well renovated shared restroom, street parking (though be sure you move it on street cleaning days but not too difficult to figure out) and a 5 minute walk to the Jolicoeur metro station. Also a big kitchen with everything you need, just bring your own food.
Laundry is not in house but laundromats are not far. Jean Coutu grocery store is even closer. Verdun is a quiet neighborhood, too. You will live apartment-style with housemates who are typically students, all good people during my stay. I saved a lot of money that I was able to put towards enjoying Montreal.
Happy travels!
