My overall stay was very good. I did a long-term stay, over 7 months.
Pros: unbeatable location. Downtown. Short walk to main metro line, close to several supermarkets, restaurants, drug stores, etc. Mount Royal just "behind".
The apartment I stayed in had a big window which flooded the apartment with light for the whole day, and offered a nice view and made the flat feel big. It had a great vibe, I really enjoyed the space. Gas stove which I love to cook with.
The host, Samuel, was really great to deal with. His response time was super quick. Whatever I asked or inquire about, he would get sorted. The maintenance crew were also very fast in coming over to help out with whatever issue I had and were very kind.
Cons: cleanliness and upkeep. The lobby and hall ways, floor garbage area are dirty. I also had to clean my whole apartment when I moved in (walls, windows, kitchen fan, etc.). The bathroom needs some tlc, the bath is peeling, black mold, the ceiling is stained. Many items were broken: the chair seats are not screwed in, big hole in the couch, I upholstered a stained desk chair, a general state of disrepair.
I did stay there for a long time, so for me, the pros outweighed the cons. If you're not too fussy, this is a fine place.
