This was our first time to Montreal. We originally had 9 people in our group and this apartment was the perfect setup.
The apartment: Rest-assured: the photos are accurate! This two floor apartment is beautifully decorated with high ceilings, 6 ample sized bedrooms, two full bathrooms, and a well-stocked kitchen. We loved having the outdoor roof deck. The dining y rooms will fit 6-8 comfortably.
One of the best aspects of this apartment is the location: right next to the St. Henri metro station and a short walking distance to bars, restaurants, ice cream, and the Atwater Market (which we loved!!). Having a metro on the orange line was super convenient for getting to Old Montreal, the Plateau, Mike end, etc.
The only downsides: when we were there, there was construction going on but at odd hours: banging from 5-7 am and then stopped. Also, please note that there is a freight train track behind the back of the apartment. A couple of earplugs did the trick for the two bedrooms in the back, but be prepared if you are a light sleeper.
Otherwise, I highly recommend this Airbnb!
