Hello ! I have spent around 6 days at Ala's place and i am going to describe my stay for you :
First and foremost is the AirBnB location which is excellent ; you are placed less than 3min walk from Mont Royal Station which is at the Center of everything (I was able to use the metro from 7am to 2am to go wherever i wanted in Montréal). Furthermore, Montroyal station is near really good restaurants and some of them are open 24h/7d (La Banquise for instance).
As for the utilities everything listed in the description was there. Moreover, for those who are not used to shared bathrooms , it is not a problem since there are 2 restrooms available and 1 shower which are cleaned rather often by the cleaning ladies (I didn't have to wait to use them for my whole stay).
If you have any questions/problems Ala is always available to help you ( i remember sending him a message at 3am and he answered me right away but i think you should avoid doing like me)
On the other hand, you can guess it but if the room is really well located it might come with some noises at night and in the morning. If you happen to be a "normal" or a heavy sleeper like me then you are less likely to have a rough night however if you are a light sleeper you might get wake up by the noise.
Overall the AirBnB has a 10 out of 10 in terms of location if you want to enjoy and visit as much as you can Montréal.
