We moved into the wonderful Auberge Saint-Antoine, which is in Vieux-Port in the lower town. It was so comfortable and the people were so friendly that we were happy to call it home for the next three nights. Our accommodations worked out perfectly in Quebec City - I got to have the Frontenac experience and then, for some reason, we got a better rate at the Saint-Antoine than if we'd booked before the trip.
The hotel was built on the site of abandoned warehouses, apartment buildings and a parking lot, and is full of artefacts found on the site during an excavation carried out jointly by the Laval University, the city and other groups. A 17th century cannon battery runs through the lobby.
The hotel is on the street of the same name. 
Above: Entrance is about half way down on the left. This picture was taken at the end of the day as we returned 'home'.
This photo shows part of the 'Cafe Artefact' in the lower lobby area. Bar is at other end. I was sitting in one of the winged chairs by the window when a passing bell/doorman stopped in his tracks, decided I looked uncomfortable and put some pillows behind my back!
The upper lobby. 
A movie theatre!
Now for some of the artifacts
We were told they are displayed in the way they were found on the site, so the older pieces from the bottom were on the lower level of the hotel and the newer ones in layers above were on subsequent higher floors. My favourite is the last one. We never did check out displays on all the floors of the hotel. In retrospect, we should have spent an evening doing that.

There were also pieces of oak caskets, leather shoe fragments, and cast iron cannonballs to name a few.
