We enjoyed a lot our stay in Paris, and we also enjoyed very much this cute apartment. It has all what we needed. The neighbourhood was really nice, with supermarkets, a french bakery shop (very important in Paris :), restaurants and several metro stops only a few minutes walking (at most) to the apartment.
Carole was really nice, she gave us very nice recommendations about restaurants (we enjoyed very much "Chez Marianne") and, although we arrived quite late to Paris, she was waiting for us. She gave us a lot of indications on how to arrive from the airport with different options.
We strongly recommend this place. It is a very quiet neighbourhood with everything you need very close and Carole is a extremely kind host. Additionally, metro "Nation" is one of the key metro-RER stops in Paris and you can go to everyplace you need in less than 20 minutes.
