We just returned from a month in France and Italy, and I have some good places to recommend.
Mas des Sentes in Nan-les-Pins: a b&b, not too far from Marseilles, Cassis, etc. Lovely hosts, beautiful house, nice large room with balcony, 80 euros/night
Cassis: restaurant Le Bonaparte. Tasty, unpretentious food. Reasonable prices. Good, friendly service. A couple of blocks away from the more touristy places right at the waterfront.
Fontaine de Vaucluse: Hotel La Poete. Pretty room, with beautiful bathroom. Lovely garden. Just a couple of minutes walk to the village center. Free, private parking.
Restaurant Chez Dominique. Very fresh and tasty , but not overly elaborate food. Very friendly service.
Vence: Hotel Diana. Great location. Helpful, friendly staff. Nice room.
Restaurant La Farigoule. Lovely ambience. Terrific food. Great service.
