We would definitely stay here again! My partner and I were in QC for a week and this apartment was perfect. The location was great, the street has lots of good places to get food/ drinks and the apartment is right over a little market. We did not find the street to be too loud on weekend nights, but we did sleep with the fan that was there on for some white noise just in case. The bed was very soft and comfortable, it is not a firm mattress if that is something you are looking for.
As others have noted, the apartment does require you to climb some stairs. Not an issue for us personally, but could be for others! The parking spot was fantastic to have - we took a few day trips out of the city and it was such a treat to be able to drive back and not have to worry about finding a spot or paying a meter. When we arrived, someone else was parked in our assigned spot. Alex was super quick to respond and made arrangements for us to park in a different spot.
There were definitely enough kitchen items, but if you're planning to make a big meal at home just know that there's not a ton of pots and pans. The back door opens onto a shared porch and we ate supper outside a few nights which was lovely.
One thing to note, the shower handle was installed backwards, so when you turn it on, it goes from hot to cold (rather as the handle is marked which is cold --> hot). So just turn it on a little bit for hot water!
