Jean's apartment is fabulous! We were there during a heat wave. And even though the place doesn't have AC, we didn't have any problems sleeping, because of its first floor location in a courtyard. It was always cool enough.
The location is great. 2 metro stops, plenty of restaurants, cafes and grocery stores. Bakery on the corner was open on Sunday as well for fresh croissants and baguettes.
We also appreciated that he let us check in early after our transatlantic flight!
