I had a great time at Christiane's apartment. I couldn't meet her, but her friend welcomed us very friendly. She(and her son Philippe) responded quickly every time I asked by text message.
Its location is perfect. We went for a walk to Eiffel tower every night. Also there are supermarkets(Carrefour, Franprix) nearby the apartment. The bus no. 69(it goes to Louvre museum, Orsay museum and Notre-Dame) stops very close to the apt.
The apartment was very clean and pretty. I liked its modern kitchen and bathroom. There were a plenty of amenities(even there were cosmetic cottons), and several welcome drinks in the fridge.
I want to stay there next time I travel to Paris!
