We would happily recommend the Plateau Suites for your stay in Montreal. My husband and I visited Montreal July 5, 6, & 7th, 2013. When we arrived at the Plateau suites, Luke the owner genuinely introduced himself and showed us where to park on the street which was free, close by and safe.
The location of the suite is very convenient to many good restaurants, coffee shops and shopping. Although it is in an area of many things to do, you are also tucked away and the street is very quiet. The subway is walking distance so no car is needed. (Luke has a binder with maps of subway routes and of the surrounding area which was helpful in getting to know the area.)
The suite is spacious and clean with amenities such as Wi-Fi, air conditioning, mini refrigerator, microwave, French press coffee maker, coffee cups, wine glasses, utensils & plates. The kitchen/living area has a couch with a two seat Kitchen table and balcony. The bedroom has a comfy queen size bed, TV, and a big window. There is plenty of space to keep your luggage out of the way in the open closet with drawers and shelves and hanging space. The bathroom is a nice size. Just remember to bring soap and shampoo. But if you forget no worries there are grocery stores close by.
We will visit Montreal again and when we do, we will definitely contact Luke and stay at his lovely place.
