The Host: Made the check-in super easy, replied quickly to every message, was super friendly, cheerful, and communicates perfectly well in English.
The Apartment: Perfectly located. Lots of Paris sightseeing reachable walking (and if that's not your thing, you have metro stations and bus stops just at your door). Plenty of restaurants/cafes nearby. Also drugstores and supermarkets where you can buy soap and shampoo for your stay and food (well equipped kitchen with the basics). Beautiful sight of Paris from this 6th floor apartment (not suitable for people with mobility issues though). The apartment is as in the pictures. It's cozy and it has access to a rooftop.
