This apartment was a really great location for exploring Montreal. 15 minutes to Old Montréal, a few blocks from the primary metro line, and very close to Rue Saint Catherines. The apartment was very clean and reasonably well equipped. We found it to be quiet, despite the closeness of foot traffic. There is some homelessness in the evenings, but you are going to see this in the core of any city. We did not feel unsafe at any point in time.
Beds were comfortable, if a bit creaky. It was very hot outside during our stay and the AC tackled it fine. The bedrooms could get a bit warmer, but keeping the doors open helped. The portable fan in the main bedroom was non functional (which someone else mentioned in a review), the dishwasher is broken, and the washer/dryer looked like it might be damaged, so keep this in mind. That being said, the price was right, the location was great, and we would most definitely stay again. Good communication and check in was a breeze.
