I really wanted to love this place, as it did have many positive aspects. However, there were several small issues and one large problem that impacted the quality of our stay.
First, the positives: the parking space was a huge plus, especially during the jazz festival. The laundry facilities and dishwasher were also much appreciated. The space itself is large and open, and was a perfect size for our group. The location is central, within an easy walk to the festival, metro, grocery store and restaurants, and only a 20 minute walk to Old Montreal.
Unfortunately, our stay was quite negatively impacted by the heat. The listing states the apartment has air conditioning, which actually consisted of two small portable units, one per floor. The downstairs wasn't too bad until the last day of our stay, but the upstairs became unbearable by the second night. The air conditioner was located in only one bedroom, and could not be moved. None of the other rooms could be cooled at all, so the temperatures were in the 85-90 degree range upstairs. None of us slept much during our stay as a result.
There were some other small issues; the floors were not very clean, the shower did not drain properly, and we found a silverfish under the bed and a house centipede in the kitchen sink. However, these things could have been more easily overlooked if not for the sweltering temperature of the apartment.
