Lots to like here.
The place: huge, spacious, nice bedrooms, very functional kitchen, clean bathroom, in unit washer and dryer, nice looking outdoor space.
The neighborhood: cute quiet, SW Montreal Francophone neighborhood (we had no problem as Anglo-speakers). Beautiful architecture, nice park just around the corner, as well as a great espresso bar and a little diner/Casse-croûte around the corner. Most importantly, it's only five minutes, give or take, to the Metro, which is fast, clean, and efficient.
The experience: clear communications and good directions for entry. Host was flexible with our check in time, which was much appreciated. We had some misunderstanding about the price- I had originally mistakenly booked for one instead of two, and the price went up significantly for a second person. They were within their rights to do that, but make sure you have an accurate price before you book.
TL;DR nice, clean place, convenient location.
