Host's assistant was very gracious and accommodating. Apartment was clean and small but efficient with windows onto interior courtyard for good air flow. Being on courtyard also provided protection from street noise. (There's a lot of street noise in Paris.). Comfortable beds. Nice shower. Didn't use the kitchen. Quiet except for a party in the building until midnight on a Friday night. It wasn't really disturbing, just friendly chit chat.
Fabulous location!!! Great restaurants, lots of shops, easy access to metro and to Notre Dame. Good WiFi.
