I stayed in Antoine's place for eight months while on a postdoc. Antoine was extremely helpful and the apartment was perfect - very convenient to my workplace and also to lots of sights and places to relax. The Luxembourg Gardens are very near, which are lovely to walk around in, and the neighborhood immediately around the apartment is full of good bars and restaurants with a lot of different cuisines. The neighborhood is quite lively, so I always felt safe walking home, even at night.
