Christophe is a perfect host. All the needed instructions were provided on time and he was extremely responsive to any request. About the apartment, it's a lovely place, perfectly locate and best suited for a couple or 3 people maximum. I'd not recommend for a family with kids as it's a bit too tight, unless you plan to spend all the time out, including meals. Anyway, it's a perfect starting point to enjoy few days of full immersion in real Paris atmosphere.
