An important thing to know about this place is that one of the bedrooms has a completely transparent glass door that doesn't provide any privacy to the person sleeping in it. There was no curtain or blinds to cover it. This might be a matter of taste, but we didn't like it, since we believe that a "bedroom with door" implies that the door will provide privacy. It is also not so great since it let's all the light in, so if you plan to sleep in late, you might want to reconsider this option. Also, since there are no markings or lines in the clear cristal, my mother in law didn't see it and hit herself in the glass door.
I have stayed in several Airbnb places in the past, and this is the first time that the host doesn't provide the most basic elements to make a breakfast. There was no salt and pepper, or cooking oil, or napkins or kitchen paper towels. This is not great for someone traveling to Montreal by plane, since they will be buying a full bottle of oil, and salt and pepper and they will need to throw it in the garbage afterwards.
Also good to know, in other places I have also had some courtesy things like tea bags, coffee filters or some coffee, but this wasn't provided either, so plan a trip to the grocery store before your arrival!
Otherwise, the place is very well located in the heart of downtown. It is also very well insulated, so despite being in a busy street, it is still very quiet. The design is industrial and very brutalist and modern. The apartment was clean on our arrival, although the bathroom smelled of humidity from the shower curtain. I am sensitive to smells and I found the smell unpleasant, but my husband and mother in law didn't find it too bothersome. Otherwise, it was very clean and tidy.
