My husband and I stayed here for our weekend getaway to Montreal. It was very clean and the location couldn't be better, right in between the old city and Mont Royal in terms of walking distance, and near tons of great shops and restaurants. However, we had to remove one star from the review because of how loud the street was at night and because of how tight the parking is- which does NOT match the picture in the listing!!
The airbnb is on the same street as lots of bars and clubs so it was very loud until about 3am every night, with the bass from the music being very audible in the apartment. We had to use a white noise app on our phones in order to get some broken sleep. The street does not quiet down until 4am.
The free parking really was nice to have, as we drove to Montreal from NY and parking in the city is tough. However, the garage is VERY tight with lots of twists and turns that are hard to make. The picture in the listing shows a nice wide open garage-- not the case. My small car was barely able to make the turns; a larger car such as an SUV will not be able to. Also, cars very low to the ground may bottom out on the steep slopes leading down to to the different levels of parking. The bottom of my car kay have been scraped on one of the turns. Overall we were very thankful to have the parking but it did not match the picture in the listing.
