Jean Paul's and Sarah's place has a lot of light and space. We thought it was a very pleasant and relaxing experience to stay there.
It is Maisonette style with an upper, small room that serves as a bedroom and a lower, big room with a very high ceiling (living room/kitchen). A nice arrangement.
We found the apartment's location to be perfect. It is on the second floor and thus quiet, but situated right in the middle of the lively neighborhood of St. Michel. There are lots of small shops, restaurants and a market hall (marché des capucins) right around the corner. It's a 500m walk to a tram stop - be it either Victoire (B-line) or St. Michel (C-line).
The place was reasonably clean, the kitchen well equipped and - quite important since we travelled there in November - the heating worked extremely well and made it warm and cozy.
The bed might not be to everyone's taste as the matress is set not on a slatted frame, but instead on a tight, metallic "net" that may start bouncing.
Jean Paul was a great host: easy going, rapidly responding to all our questions and always willing to help.
