Had four lovely airbnb experiences in France...all were 'shared' apartments/homes as opposed to 'on your own' apartments...
Bright, cheerful, up a few floors, less than a 10 min walk to Eiffel, just a minute from the metro - Cambronne (and only one change to get from CDG). Nice large room, awesome bathroom, small kitchen, lots of restaurants nearby, little street noise but mostly quiet. We walked almost everywhere from here and Memona, the owner, was very nice...small language barrier but she spoke English very well.
Sorry - actually this one was sort of self contained. It was more of an in-law suite. Secure parking behind a locked gate, about a 15 min walk up to the fortress or to the city center. You could actually see the fortress out of one of the high windows if you craned your neck. Little fridge and microwave, but no way to cook a meal. Very clean, nice automatic blinds that cover all the windows. Quiet residential neighbourhood. Marie-Do didn't know much English (and we don't know much French) but we had enough to get by.
Another nice little room in a lovely private home, beautiful huge private shower (if I could have brought that shower room home in my luggage, I would have!) and separate private toilet. Quiet residential neighbourhood, secure parking behind a locked gate. Carman had a little breakfast for us every morning - fruit, juice, coffee/tea, bread. And use of the kitchen facilities (I cooked supper one night). Also offered tea and coffee and snacks in the evening. Even did my laundry! Unfortunately, we didn't explore Salon, but it was centrally located for trips to Les Baux, Aix, Pont du Gard, Nimes, Arles...and lovely hostess to chat with. She wasn't there when we left and when we got a few minutes away, we passed her in her car, so we had to turn around and go back so we could say a proper goodbye - she was a lovely person!
Another nice stay. Parking was a little funny as you just parked on the side of the road, but never had an issue getting a spot. Gated community, so after 8pm you would need a code to open the gate. Diane told us a 'back way' to get to St Paul de Vence and we were there in about 10-15 minutes. Close to other areas as well - a bit of a drive to get to places like Monaco or Nice, but well situated for exploring places like Vence and the hill towns like Gourdon...and close to Antibes. Again - you could use the kitchen and they supplied bread and juice/coffee for breakfast. Also had good ideas about what to see (Gourdon) and what to skip (Grasse).
