My mother and I recently stayed here and very much enjoyed our time in QC. The one thing and visitor should know is that the apartment is on a main road which does mean there is a bit of street noise even early in the morning. If you are a light sleeper I'd wear ear plugs or something to lessen the noise.
The apartment is lovely, clean and having a dedicated parking space is incredibly convenient. The location is also great. We were able to see fireworks that were going off above the old city from the apartment balcony.
