It was a beautiful apartment and so much cleaner than we expected. Bathrooms looked beautiful, and the rooms were spacious. The stairs as mentioned were very steep, but it's fine and kids love it.
It was very clean everywhere, and there were plenty of towels and cooking utensils (plates, cups, etc) and just necessary amenities. Although there was no ac, it wasn't very hot (and just slightly cold in the basement) at night.
The beds (including the sofa beds) were very comfortable, and there were enough sheets, blankets, and pillows. Overall, a great location and apartment. Highly recommend paying for the parking space because it's right infront of the apartment (and it seems difficult to find parking elsewhere). The host Philippe responded very quickly and gave thorough directions.
The only few downsides were that it was just slightly musty in the basement when we first entered and the front/back doors had no coverings/curtains on the windows so anyone can look in/out through those windows. This makes it slightly uncomfortable for the person who sleeps on the sofa couch in the living space or if you have personal belongings in the living space since it can be seen from the outside. Otherwise, it was a beautiful, clean place!
