There were 6 of us (1 couple and 4 singles -- in our 30s and 40s -- all runners, training for various Fall marathons) staying at the house for a 3-day weekend. Lots of positives here. Fast and easy communication with hosts. The location is ideal -- on a quiet street, 5 min walk to the northern edge of the Old Town, and ideal for accessing various flat running paths. The apartment -- 2nd & 3rd floor of a separate standing house -- has a lot of old charm and character -- pretty much exactly what you see in pictures. The house has a well equipped kitchen, though we didn't cook. It's Montreal -- so many great restaurants! Towels, linens -- all good.
The house is big! Huge living room. Big attic with 3 big beds -- lots of space. It can fit 2 couples and 3 singles -- no problem.
Just two things to be mindful. The house has 1 shower, which can create a bit of a bottleneck. The bedroom adjacent to the living room, as of this writing, doesn't have a door, which could create discomfort, especially for a couple, and if one is trying to sleep, while others are talking/watching TV in the living room.
All-in-all, I recommend this place!
