I highly recommend this is lovely little nook! Very safe area, close to multiple metro and bus stops, within walking distance (20 minutes) of Palais Garnier and Fragonard. Parc Monceau, a small park just a block away, is worth exploring, as is Musee Nissim de Camondo, a beautiful mansion with all the original furnishings that gives you a true sense of what it would have been like to live there.
I arrived very late and tired, without my luggage, and Marie welcomed me with some nibbles and lent me some clothes - so very kind!
It’s on the 5th floor, but after several days the 100 stairs got a lot easier!
