We stayed here for a month and couldn't have asked for a better experience. Sylvio and Carolina were extremely communicative and helpful. The place was exceptionally clean, beautiful, and well-equipped. There were multiple times that we were pleasantly surprised to find something we needed in the closets.
As all the other reviews mention, the location can't be beat. You're steps away from everything your heart desires, and it's the best place to go for walks.
Probably the only thing to be aware of is that the bed is right next to the street, so the garbage collection can be quite noisy. If you are a light sleeper, bring earplugs. (I was fine but my wife struggled with it a few times).
We were so sad to leave. Whenever we come back to Quebec City this will be the first place we look to re-book.
