Ray's place is exactly as described. My wife and I spent four nights there and had a wonderful time.
The check-in directions were very clear, and Ray even includes a detailed sketch of how to get from the parking lot across the street to the apartment. We parked our car for the whole time and were able to walk everywhere in Old Quebec. There are several restaurants on the block, and it's an easy walk on flat land to Petit-Champlain where there are lots of other options in the area. It also only takes about 10 minutes to get to the Dufferin Terrace, which is a wonderful place to sit during a summer evening.
Ray's place is close enough that we could head back to the apartment for a mid-day break if needed, and then head back out again later. This was especially nice on one of the days were it got fairly hot (upper 80's F), but the a/c in the apartment worked extremely well.
We would absolutely love to stay here again when we're back in Quebec City, and I've already recommended Ray's place to several friends!
