The stay was wonderful. The apartment is so nice, neat and light, we really felt at home there. It was perfect for a couple. Its heading towards a quiet small street so no disturbing trafficsounds. The 6 floors were not a problem at all, the stairs were actually very easy to climb.
The apartment is located perfectly in a nice area that was not touristic at all but with many bars and restaurants. But still only 10-15 minutes walk to wonderful Marais (or a few metrostations).
Jean is a perfect host, easy to contact and very willing to help us out during the stay. And Paris is such a great city. I would recommened this place to anyone!
