Great stay at Hiroko's apartment. I went with my daugther so we slept both at the top and bottom levels of the place - very comfy. The neighbourhood is very lively but not noisy at night, and the best of Paris is at a walking distance. A paradise for art (and restaurant) lovers. The views from the apartment are fantastic, including a bit of the Eiffel Tower. The bathroom is artistically deconstructed along the stairs from the bottom to the top levels; an arrangement that was fun and practical. Very small kitchen but who wants to cook having Paris at your feet?
In summary, a highly recommendable place for one or for a couple.
