This is a great spot very close to downtown and public transportation — a great, affordable way to see a lot of Montreal! The rooms are comfortable with good privacy (locks on doors), kitchen is reasonably stocked, and Roger is very helpful and responsive. Check in/check out, including bag drop off, is all very easy. The snacks in the kitchen are a nice touch.
To some extent, you’re getting what you pay for. I’d recommend for travel, if you want to use it just as a place to sleep while you do other exploring,m during the day, but not as a relaxing spot in and of itself. It is sufficient.
I would just note that the hallway wooden floors are beautiful and very squeaky. There are two other Airbnbs in the apartment, so people will be coming and going, which may be difficult if you are a light sleeper.
