The location to the center of Paris is phenomenal! We interacted with Bruno during our stay and he was attentive, responsive and kind. He speaks only French, so a translator app is a must, if you don't speak French. The apartment was very roomy (a rare find in Paris). Overall, we enjoyed our stay very much!
Be aware - if you have any mobility issues, this apartment may not be for you. There are lots of stairs to get to the apartment and then the apartment itself is on 3 levels.
