Great large loft apartment and a great location. I stayed a little over 5 weeks with my dog and I didn't have any issues, aside from the random fire alarms. The location is great, walking distance to downtown, old port, and Griffintown. There's a small gourmet grocery store close by, but the other big groceries are a short 10-15 minute walk away.
I was told about a week into my stay from a resident that the building wasn't supposed to have AirBnb guests and to not mention to any other residents - so that was weird. Not sure if it's accurate, but definitely something to mention.
Some other random things in the apartment I would've changed - there was only one wine glass, no lighter or matches, no pasta strainer, the baseboard for the cabinet hit the dishwasher, so the dishwasher door actually couldn't open unless you took the baseboard off. The shower also doesn't have anything but extremely hot water, if you like cold or warm showers then I'd look elsewhere.
