Simon's house was a great place to stay, it was clean, it was safe -- there's a nice sized living room and kitchen to be in as well as a cute little balcony out back in a private alleyway.
I can't stress this enough, however: the location PERFECT. This was my first trip to Montreal and I really wasn't aware of how walkable everything was and the fact that Simon's house was really in the middle of everywhere I wanted to go was a blessing.
