We had an amazing stay at Christophe's place. The location is even better than we expected, just a short walk to old Quebec. Once we had parked we only got in the car once to drive to Montmorency falls and iles d'Orleans, we were able to walk to everything else we wanted to see.
There is also a stop for the hop on hop off tours just a block from the apartment.
Christophe also provided tons of pamphlets to help us plan our days when we weren't sure what to do. The apartment was very clean and well stocked with essentials.
I wouldn't hesitate to recommend Christophe to anyone, and would look forward to staying another time!
