I love Quebec City. Love it. It has enough Europe flair to make me feel chique being there and enough Canada to make me feel at home. If I spoke French even a little bit better I would move there. The old city is tight knit and comfortable. Lots of hills (not surprising) and views of the water. We did a few things in the city but I think the best thing we did was a walking tour. The tour started at Chateau Frontenac, once the governor's residence and now a luxury hotel. We then wandered down through the Seminaire de Quebec. It was full of school kids and so quite loud and full of echos but really beautiful.
We wandered down outside the city walls and into Place Royal. Almost all of the land beneath the city walls is reclaimed land. The area we wandered into was built to recreate what the city would have looked like in Champlains time. This was a requirement the city fulfilled in order to receive UNESCO world heritage classification.
We ended with some shopping (of course) the main tourist-y shopping street was directly below the chateau and was extremely busy.
