Our experience at Julien's flat was extremely positive. Julien was in frequent communication with us before our arrival, so we knew exactly what to expect and how to contact him and his family if we ran into any trouble (not that we did). In the end, we actually did not get to meet Julien, but his family greeted us and made us feel very welcome. They had even gone to the trouble of getting us maps of the area and inquired about the best deal for metro-tickets on our behalf. The room was comfortable and clean. We were able to have breakfast on the balcony every morning, which was lovely. And we had full access to the kitchen, which made our lives a lot easier. On top of all this, the room was great value. If you are going to get an airbnb in Paris, you should try to book this one.
