This is a lovely apartment for your stay in Quebec. I stayed here with my daughters (aged 11 and 8) and we were perfectly comfortable.
The apartment was spotlessly clean and has a brilliantly equipped kitchen with everything you need, even an umbrella!
The apartment is located in the Saint Roch district which is very hip with lots of nice bars and restaurants. It is right above a nice coffee shop and less than a 5 minute walk to a supermarket. It is around a 10-15 minute walk to the central attractions of Quebec, the Chateau Frontenac, Place Royale and so on.
We were able to leave our cases on arrival until the apartment was ready and everything was perfectly smooth on arrival and leaving.
