My family loved the St. Denis st. apartment during our short sight-seeing trip over Thanksgiving. I wanted to give six stars to the location if I could - the apartment is literally in the heart of a street lined with bars, restaurants, bakeries that we would walk each day to explore. The food are so good and so much better than the downtown tourist-trap places. You don't even have to go far as the vegan restaurant at the ground floor of the building is top notch, "best ever" according to my daughter and my wife. A grocery store is also just 30 meters away.
The place is a floor-through apartment. We love the convenience of having three separate bedrooms, full-size laundry, and individual adjustable thermostat in each rooms. Parking is in the back alley, and you would walk less than 100 meters around to the front of the building to get in, which does not bother me at all because we quickly discovered that so many things are walkable from the place and we do not need to take the car out more than once a day.
One thing to note: you will climb a flight of stairs to reach the the apartment door on the top, but the top step is about 2 cm taller than the rest of the steps, which presents a trip hazard. Every one of us tripped the first day we climbed the stairs at the top. While by day 2 we've learned to be careful at the top, hopefully this helps future guests to pay attention.
I also enjoyed the quick communications from host Stanley. You could tell the place is very recently renovated and everything is new. Stanley always answers messages within a minute and promptly came by to drop off some supplies within an hour.
