Fantastic location! Close to the Frontenac, board walk, restaurants, coffee shops, petite Champlain. Definitely do not require a car if you plan on touring Old Quebec only. If you do bring a vehicle, paid parking is across the street I recommend parking on level C for easiest access to the exit in front of the apartment.
The suite itself was very clean and in excellent condition, communication with the host was excellent. I would highly recommend!
