We stayed at Chantal's place for six nights and it was absolutely great! The apartment is rather small but has a charming atmosphere, it is clean and very nicely furnished and decorated. You can use a courtyard/patio, which is really quiet.
The apartment is located in a nice neighbourhood in the 18th arrondissement, right next to metro and bus stations and several supermarkets, bakeries, bars and restaurants. There really is everything you need! Also, the communication with Chantal is very easy and friendly. We would definitely recommend staying at her place!
