I booked John's place on behalf of my sister and her group.
My review is based on their feedback.
Location-wise this is a very ideal location as it has access to Berri-UQAM which is connected to three separate lines making travel to different parts of Montreal very convenient. There were also several restaurants within walking distance to the property.
The room itself was beautiful, and very spacious. The bedding was quite comfortable, while the noise outside was barely noticeable.
Overall, this is a place worth considering when visiting Montreal.
