We booked it last minute for an impromptu trip to Montreal. The place was lovely and the location is 10/10. The apartment is a great size, and the views from the wall-to-wall windows are amazing. The place basically offers everything that you really need however here are a few points to consider if they are important to you.
The carry-on life for Strollers/wheelchairs is never working. As we were traveling with a 15-month-old, carrying the stroller through the stairs (though only 5) was a challenge especially during the nights when the child was sleeping in it.
Wifi was very clunky, even though there were 3 different wifis provided by the owners, seemed like none of the routers are actually in the condo however are shared amongst multiple units. Not sure the reason for the same however if Wifi is very important to you then it can be a deal breaker.
The mattress on the bed is the cheaper one which has started to bend a bit more towards the head side, so much so that it almost felt that I was sleeping with my head below the level of my legs if using only 1 pillow, not much of a challenge though as we then slept on the other side which was fine.
