I just spent three nights in Chachou’s flat in the 7th arrondissement of Paris. The apartment was very nice and the communication with Chachou perfect. The flat is ideally located between the Eiffel tower and the Invalides. It is on the ground floor so extremely easy access. The only drawback I found was that there is very little natural light through the two windows, a not uncommon problem in Paris. The interior lighting is very adequate and for a short visit where one is out almost all day, it would not be a problem at all. Othewise, the studio is perfect
