The unit was very clean and spacious. The only negative comments i could think of is that parking can be quite a problem at certain times of the day. Lots of stairs so be prepared if you have luggage.
But overall we really enjoyed our stay, the unit was large enough for the whole family to be comfortable and close enough to old Quebec that you could walk there if you wanted to, but i would recommend taking a taxi.
Market and restaurants are near by and Stephanie and her whole family were great hosts. If i were to return to Quebec city in the near future i would definitely stay here again.
