Jaime's place is great for location- it allows you to walk to the major parts of Quebec City fairly easily. Another excellent aspect is the parking spot available (note it is not directly at the building, but behind across the street, but viewable from the apartment).
It's a very simple set up, so if you're looking for fancy or a place with lots of amenities I would look elsewhere, but if your goal is to spend time out and about then it does the trick.
As mentioned by others the stairs are tricky, but we managed to get fairly heavy luggage up, so as long as mobility isn't an issue it's doable.
I would definitely recommend Jaime's place for those looking for a cheap place to stay, in a walkable location, and don't mind the look of the place.
