I spent two months at Jin's place and it was setup for a decent long term stay. The balcony is a high perk of the unit and it's bathed in the afternoon sun with some nice views over the city. The bedroom is rather large and the desk is a nice touch, especially as I was working from it.
The place is VERY minimal. There's currently no blinds on the main living area window so you lose a sense of privacy at night if you want to hang in there. The internet is also a hit or a miss and can be rather slow at times. It wasn't something I highlighted to the host, as it didn't bother me and nor did I have an issue with it, and is worth noting if you require it.
Location can't be beat and that's what truly stands out for this place. Within a 20min walk, you can get to major locations (Old Port/Montreal, ChinaTown, Atwater Market, etc) with a metro stop close by. You are even a 10min walk from the train station and Bonaventure bus station that includes busses to take you to the south shore.
