Our family had a great stay !
The location was good. We walked everywhere in Old Quebec. The parking took some skill to get in and out, but having own parking space was a great bonus.
The unit was well stocked, minimalist, and basic but updated/renovated and clean. We had arrived from a long driving trip with kids , so, having a new/clean washer and dryer was such a nice treat.
The place is on top of an art gallery. There are 2 floors above unit, but there was really not much noise. There is a bit of noise from the restaurants down the street at the front of the building (bedrooms are in the back), but they close relatively early so it was quiet at night and in the mornings.
We were there at the end of the summer, so the weather was starting to cool, but we still needed the fans in the evenings and at night (unfortunately, no air conditioning in this historic building, so, the place probably would be quite hot at the height of the summer).
Overall, we had a great stay!
