I would not recommend staying at this Airbnb - the principal issue being an unfriendly and actually quite aggressive host.
Midway through our stay Helene arrived to tell us we had to leave as she had other guests coming - she had incorrectly read her diary so fortunately we did not have to leave at that point. We had arranged with Helene for a late checkout on the day of our departure. Unfortunately on the day we were due to leave we returned to the house 3hrs before our agreed check out time to find all of our bags including our valuables, passports and money moved out of the rooms and the doors unlocked. Helene said she had again double booked another family and that we had to leave so they could arrive. Unfortunately this meant that we had fifteen minutes in which to pack our belongings and leave the home, we ended up sat in the airport for hours waiting. Helene in this time was rude, quite aggressive and was following us around saying we should've checked our phones for her text message telling us we had to leave (we were visiting family and had no signal). We were also accused of breaking a bed in the property, something that on further questioning Helene said was a longstanding issue that had occurred on a previous stay. A sad end to an otherwise great stay in Montreal
In summary, lovely house, bad host. Book with caution.
