My favorite aspect of the flat are the windows looking out to the street from the 4th level (3rd floor). You know you are in Paris with the historic Musee Carnavalet building and the other buildings at the intersection.
The location is excellent. Close to Place des Vosges and walkable to many places. But also in every directions different bus stop/route only 1 or 2 blocks away.
I have stayed there on 3 visits. The host is helpful and provides excellent information regarding the neighborhood. This last visit my sister, an excellent cook, was with me. The first night we went to the nearby G20 Supermarche for essentials and with specialties (like cheers from the cheese shop, a roasted chicken, etc) had many fine meals at “home” spending less than 25 Euros a day on food—for 2!
An excellent choice for Paris!
