Would not recommend - far from Tourist Area, unsafe, management is responsive but unhelpful.
Location - this apartment may be considered in "Old Quebec" but it is a significant walk uphill to get to the walled city, which is where everything is. It would be a 40 min hike up a large embankment to get to the Chateau Frontenac. It is also in a rougher area of the city, it was the first time I felt unsafe in Quebec City. My cab driver was very unsure about leaving me here. I would not recommend this location for tourists. Taxis and Ubers are not super easy to come by in Quebec City let alone in this part. Stay in the middle of the action - you will have a better experience.
The bedroom also shares a back patio with a restaurant and is very noisy until 11pm. It is a very noisy building with thin walls and floors.
Apartment - it is a beautiful apartment with nice ambiance. However, it was not stocked with coffee, tea, sugar, or essentials (only 2 rolls of Toilet Paper for a week stay), the furniture was broken and needed replacing, and the appliances only kind of worked. It was clean, but the bathroom has black mold growing on the drains and curtains.
Management - they are responsive and decently easy to get ahold of. Unfortunately the entire road in front of the apartment building was ripped up and access to and from the unit was intermittent and scary at best. You had to be escorted through a construction site and the bulldozer had to be stopped so you could get by. We got trapped on the last day for an hour (I canceled 3 days of my stay due to the 6am construction start and constant shaking) and had to be evacuated from the building by the construction team. 2 days in, I stepped on a nail because there was no access that wasn't through the construction site and I had to get a tetnus shot. I initially thought I could tough it out, but after getting trapped, having to get a shot, and the constant noise I decided enough was enough and to cancel my stay.
While the apartment managers were deeply apologetic and requested multiple times that I remember this was not under their control - I felt that $200/night was too much to ask for a unit that was inaccessible and a safety hazard. They allowed me to cancel the last part of my stay with a refund for the days I did not stay, but refused compensation for anything else. They did offer to move me to a different - even farther away - part of the city or give me one night (of 7) free for the inconvenience. I asked for a full refund for the injury, the evacuation, and the constant noise. It was refused and I paid full price to stay in a dangerous area, full of construction, with safety hazards.
I also found that while they were responsive - there was very little willing to be done. It felt like it was a combination of "well you chose this apartment...live with it" and "its not that bad just deal with it". The compassion and customer service was lacking. I also found out that the City recommended for those who live on that street stay elsewhere during construction - and put them up in hotels. Yet the owners of this AirBnB were more interested in $$ than the comfort of their guests.
Due to the location, broken amenities, noise, and lack of compassion - I would not recommend renting this place. Spend the money to stay up on top of the hill in a cute little hotel or auberge in the walled city. This place will just make your trip challenging.
