Diane wasn't home, but her sister Marjorie was. She was really sweet and warm. The apartment is really sweet, and cosy, and we felt at home, right away.
Goncourt metro station is right next to the apartment, so getting around was easy. There are also a bunch of great cafes, bakeries and restaurants around the area, as well as a supermarket around the corner. Walk for about 5-10 minutes and you'll find plenty of great bars, as well.
All in all, my wife and I had a great stay, and I recommend this place for anyone coming to Paris.
