My wife and I travelled to Paris with two teenage daughters, and we all loved our stay at Arielle's flat. It was so charming and in a wonderful section of Paris. The food options are amazing just a hop away and the cafe dubillot across the street is a nice place to eat, have coffee or drinks and people watch. It can get a little noisy at night if you keep the windows open, but if you want to enjoy Paris night life, it's perfect. The windows are double insulated so they are good sound barriers if you need your sleep as the cafe doesn't close until midnight. Our contact was Alex (Arielle's fashionable father) who has a lovely dress shop downstairs. He was friendly and perfectly accommodating yet unobtrusive. He speaks english well and had good suggestions for us.
We stayed at other places in Paris, but this was our favorite and we hope to return.
