You should be staying here primarily for the location, which is pretty amazing. It's located right in front of a small but cute park. There are plenty of bars and delicious restaurants just a block or two away, if that.
Other places like the Notre Dame Cathedral, Old Port/Old Montreal, all less than 20 minutes walking.
The only place we took Ubers for the entire 5 days were for the Botanical Gardens/Biodome, which were worth seeing and reasonable fare prices.
The apartment itself and room are qauint and clean enough. Adequate I'd say. It's sometimes obvious that this is just an apartment and someone's room we were renting in it. We barely ever saw the other person who lived there (it seemed like all of us were gone most of the day). Warren had great communication. If you are on budget and want location over everything, and are willing to walk up to 30 mins to get to places like the Fine Arts Musem, this is a pretty great stay.
My only complaint were the size and comfort of the bed, minor cleanliness issues, and being told we needed to be quieter when returning at 3am even though we thought we were.
