Ninon's flat is located in an awesome area in central Paris, close to the metro and to a bunch of nice cafes and restaurants. It is, however, quiet, since it overlooks a sort of inner patio. My friends and I stayed for a weekend and we absolutely loved the place, it is comfortable and cozy, with a bohemian feel to it :) Communication with Ninon was always easy, she let us leave our luggage in the flat during the last day until we took the train in the evening, and she also left us some juice and biscuits for breakfast. I can totally recommend staying at her appartment!
