First off and foremost, Winton and Claire's condo is in a great location. We found it extremely easy to get to various amenities within downtown Montreal as well as public transit. Parc Jean Drapeau in particular was easy to get to, requiring a short walk and then a few metro stops.
With that said, prospective guests would do well to note that one of the bedrooms features a skylight that lets in a significant amount of light, even at night. I cannot understate enough how much light comes into this room. Anyone who requires significant darkness would do well to stay in the other bedroom if they can help it. If privacy among your party is an issue, guests would also do well to note that the door to this room features a large glass cutout, meaning anyone within the living room has an easy sightline into the room.
Despite these issues, the location rules and we found that it was a clean place to stay in. If you'd like easy access to downtown Montreal and can deal with some of the idiosyncrasies of the condo, consider booking.
