It was a very nice place to stay at. It was the perfect size for one or two people, but absolutely no more. The location was great, and it was near a ton of places to go out and discover. The value was also very nice.
Erinne was incredibly responsive and even allowed us to check in much earlier than the typical check in time!
The only downside that I can think of is that noise from the neighbors can be heard throughout the day (as will your sounds be heard by them) due to somewhat thin walls, but that's how it is with any apartment building.
I would definitely recommend this place to anyone staying in Montreal, the place is great, as is the host, would definitely stay at again. :)
