Stayed for 4 days and 3 nights. Overall, my party and I enjoyed our stay. While there was construction on the street, which made getting to the apartment a little bit difficult, this was beyond the control of the host. Checking-in was a very easy process.
The apartment was overall fairly clean, and if you'd like to wash any of the linen/towels provided, when arriving or before departing, there is a washer and dryer which is nice. It is a very spacious apartment. The location was quite nice, only a 20 minute walk to Old Quebec and there are a number of restaurants and bakeries in the immediate area. Having a parking space, which is located about a 5 minute walk from the apartment in a parking garage was also very convenient.
The only complaint was that the Wifi was unusable if you weren't in the living room or kitchen.
I would definitely stay again for future trips to Quebec City.
