Carole's place is very nice, as is she. It's a good location to connect to everything in Paris, just a few minutes from 2 metro stations and bus stops.
Supermarket, restaurants, banks with ATMs are nearby. The building is newer than most in Paris, with elevators and safe entry. The bedroom is nice and quiet, since it's not facing the street. Carole is not around much so you never need to wait for bathroom or anything else. I would recommend her place to any solo traveler passing through Paris.
