This reminded me of Airbnb version 1.0, where you stayed at people's places while they went off on vacation, as the owner lives here when it's not being rented out. That said, everything from start to finish was well-run and top-notch. This is a fantastic location for our family of 3's exploration of Paris, the apartment is well layed out and has personal touches - basically this "feels" like a Parisian home, because it is. The area is super safe and residential, so great for families, and there are a few markets, pharmacies, taxi stands and metros all within 2-5 minutes. There's also fantastic restaurant called En Bas at the end of the Avenue des Ternes, with terrific food and some great natural wines, if you don't want to venture far or cook at home.
Overall VERY recommended.
