We stayed at Eric's airbnb last year and chose to come back as we absolutely loved it. The apartment is huge and the location is ideal to go out and visit Montreal. It is a great place if you're coming to have fun and go out at night. The bar downstairs is a cool place to end the night. If you want a quieter weekend though, this might not be the right place as you can kind of hear the bar.
In terms of comfort, the 2 double beds are good but the sofa bed in the small room is not really.
Eric is a great host, very easy going and always available if need be. He was also very accommodating and let us stay a bit longer on Sunday.
The only big missing thing in the airbnb is one or two extra sets of keys.
Overall, we loved our stay and would love to come back!
