The apartment is in an ideal location near Rue St-Jean and Old QC, and there is plenty of space for two. The bathroom is a little narrow if you're unaccustomed to city-size apartments, but we had no problem with it and the water pressure is great. There isn't A/C similar to most places in the area, but there is a tall quiet fan that helps cool down the place a bit.
As some review(s) might mention, there is construction right next to the apartment until October that makes finding and accessing the place a little annoying--on our trip, we could only access the back door, which was kept unlocked but stuck a bit. Kyle gave us instructions and pictures on how to access it, though. No construction noises on the weekend when we stayed.
Overall, very clean apartment with a helpful host. We'd stay here if we visited QC again!
