We stayed at Rodolphe's place for seven days. The place is a tiny studio, very cute and cozy and has everything you will need to rest after a long day. It's on the first floor (second for Americans) and you need to climb one flight of the spiral staircase.
The studio was very clean and completely prepared for our arrival.
There is a couch/futon that unfolds into a bed.
The kitchen has everything we needed. And, as we stayed quite a few days, we had to cook there. I didn't experience any shortage of kitchen stuff. The only thing that wasn't there is microwave. But it wasn't an issue for us at all.
As in many places in France, there is no air conditioner in the studio. But we opened windows and had a wonderful breeze.
Secured Wi-Fi worked all the time.
The area around is safe. Has many stores, restaurants and small cafes. Subway is literally few steps away from the building, so as buses. In 15 min you can be next to Louvre and other tourist attractions.
Overall, the place is not fancy but conveniently located and comfortable for living.
