Christiana's house is very nice, well decorated, provides everything necessary making travelers comfortable. we enjoyed staying there very much. It's definitely worthy.
Bus stations, subway stations are nearby. We even walked to Musée d'Orsay and Tower Effile.
We like the Boulangerie Nelly Jully, which is next door to Christian's house, we bought bread, cake, salad and sandwich there, to make sure we have enough time in museums, but time was still not enough.
The carrefour nearby was very convenient. Some mornings, we cooked some easy seafood and vegetables, made coffee, bought croissant to enjoy our breakfast.
Besides, Christian made some brief negotiations with us in advance. Philippe welcomed us, he was very kind to help us when needed.
