We enjoyed our stay at Vivi's place.
The apartment was very clean and quite spacious for family of 6.
Very easy check-in and Vivi is great with communications.
One thing to note, as mentioned by another as well, AC is located in the living room while fans are available in all rooms. Though I think it may only be an issue during summers as it's mainly cold in Quebec and these apartments have central heat and humidifier.
Overall, we enjoyed out stay and accessibility to Old Quebec. Thank you again!
