The house at Lachine was excellent for our group of four adults and a dog. We had more than enough space to spread out. We made use of the kitchen and large dining area. The lounge/living room was a nice gathering spot in the evenings to watch tv.
The location is fantastic. We walked the canal, visited the local restaurants, and the house is in a good position to drive in to downtown Montreal.
Vlad is one of the best airbnb hosts we have had on our cross-country trip. He communicates in a very timely manner.
The only concern about the house would be for people (and dogs) with mobility issues as you must climb stairs to reach bedrooms and the full bathrooms. Other than that, it was a wonderful stay.
