If you just need a place to sleep that is close to a Metro station, right next to Rue St. Catherine, with great restaurants and nearby places, then this is the place for you... You just need to be okay with a less than good place.
It wasn't that the AirBnB was bad per se; however, there were a lot of minor detractors. You may find some leftover hair in your bed, but you'll only see it if your in a room where the lights work. There was a full kitchen, however the taps had only one pressure: explode. There was a sofa bed... That was very stiff and did not come with a proper set of bed sheets. There were also some toilet clogging issues, so practice up on your plungering skills.
Once again, I cannot stress enough how awesome of a location this was if you want something in the heart of Downtown Montreal. Dave was a very responsive host as well. Just be aware of what's above, and you'll be alright... Oh also, the three flights of stairs weren't that bad if you are able-bodied. 3.5/5
