We had a lovely time in Quebec and Celine's apartment was so conveniently located. It is just off Rue de St. Jean which has restaurants, bars, bakeries, shops, and a beautiful character. The only negative to the location is that the building was being remodeled and I was hesitant at first about how secure it was. However, we never had any problems and I am very confident that it is a safe, wonderful neighborhood.
The apartment itself was perfect for a couple or individual. It has everything you need. And the parking pass was a lifesaver! Just be aware that the garage is about 5 or 6 blocks from the apartment so plan your drop-off accordingly. We drove to Quebec from Montreal, so we left the car in the garage for two days while we walked all over the (very walkable) city and then used it to get out to Montmorency Falls and Ile d'Orleans.
We would definitely recommend and would stay here again.
