Mathilde and Jean-Pierre's place was beautiful. Location is very central and walkable to almost all major attractions in Paris. Downstairs you can find multiple supermarkets, restaurants, and pubs/bars are just a few steps away. Surprisingly, it's quiet at night.
I stayed in a one bedroom unit with a private bathroom on the same floor with them - it was a true private bathroom! The building is very secure, and the WiFi and everything worked great. Mathilde and Jean-Pierre traveled extensively and lived in San Fran before and were super friendly and easy to chat with. Mathilde offered a lot of good suggestions that helped shape my Paris experience and I can't thank her enough.
Overall a great experience! If you are looking for a home in Paris, Mathilde and Jean-Pierre's place is a very good choice!
