Pros:
The apartment is clean, bright, relatively fresh (ie in summer). It's located walking distance to downtown and 1 block from the main metro station and Bixi bikes.

Good size apartment with the right amount of space. Enough (clothes) storage space for a 2 person short term stay, or 1 person long term.

Ones - the owner - is a caring host and helps out where needed promptly.
The place is fairly well stocked.

Cons:
Despite the location being walking distance to some good places, it's also bordering on a less pleasant area (ie social housing area). Nothing dangerous, but it's not like being in the middle of plateau area.

There is no air conditioning, so it can still get hot in summer. And when you want to keep the windows open in summer, it's very noisy from street traffic - the bedroom faces the street.

In addition - and this was my bad luck - the entire 6 weeks stay, there was construction going on on the road right in front of the bedroom. But because of the heat I needed to keep the windows open.

Also - and this may be a pro for some - the bed is extremely soft, not good for bad backs. And squeaky.
