Louis's place was lovely. My boyfriend and I only stayed one night, and we were very pleased with it. The building the apartment is in seemed very secure. Also, the neighborhood around it had lots of restaurants and shops. The apartment was clean when we arrived, and it's so nicely decorated. The WiFi was easy to connect to and we were able to stream from Netflix just fine.
It is on a city street, so it wasn't the quietest at times. It was fine through the night, but it got loud again early in the morning. My boyfriend and I are heavy sleepers and didn't find it to be a problem, but I could see it being an issue for lighter sleepers.
It's only a short drive away from Old Quebec, too. We stayed during the week, so there was no free parking. There are a few nearby paid parking garages within walking distance, though.
We'll definitely keep this place in mind the next time we travel to Quebec!
