The location was of he Airbnb is good. It is located relatively close to a metro station that brings you right into the center of Montreal quickly.
Unfortunately that's the only positive thing to say about my experience in the appartment.
The appartment had a bad smell. The shared areas were unclean, everything had a greasy film on it. Even our private room hasn't been thoroughly cleaned. The outside area (wooden terrace) was unusuable.
After sharing the unsatisfaction with the host we could not agree on a solution. He offered me a partial refund under the condition that i do not leave a negative review on the appartment. In addition to that he threatened to leave a negative review on my personal profile should I not follow his instruction and decide to leave a negative review on the Airbnb anyways.
I feel like this is an important information I have to share regarding the many positive reviews (or lack of negative ones) left on the Airbnb. I do not want to accuse the host of doing this regularly. Still I felt the need to share this practice of the host. Needless to say this kind of behavior/communication is unprofessional and lacks integrity and respect.
Taking everything into consideration I would recommend you to book a different Airbnb in Montreal and save yourself a lot of nerves.
