Marc and Pauline are fantastic hosts. The apartment is bright and spacious. Marc speaks very good English and is happy to offer local tips. There were a few issues that were resolved quickly (the heat wasn't working, the hot water wasn't working).
The apartment is in a very nice neighborhood above a delightful bakery. 15 min walk to Eiffel Tower, 20-30 min by car to other major sites (museums, etc.).
When I first read the listing, it sounded as if the apartment had a private entrance/private access. Just so everyone knows- it's a shared entrance and shared space (living room, kitchen). There is a private wing with 3 bedrooms, a shower room and bathroom. It's very nice & comfortable bedding.
