I really appreciated the apt 409 for a few days. The flexible check-in is a plus for late arrivals from the airport. The flat was very clean, accurate and well equipped. Additionnaly, Kim is a very kind host.
It is to be noted that the location is a bit far away from the metro Cote-des-neiges (about 10-15 min by walk) but there are two bus lines that are very useful (11 to Mont-Royal Parc and 165/166 to downtown).
I would highly recommend this place though !
