My wife and I went to France in May 2014, flying into Nice for three nights before going on to Provence, then to the Dordogne and ultimately Barcelona. In Provence, we had a car and used Lacoste as a homebase. We were able to easily day trip to St. Remy, the Cotes du Rhone (Vaison la Romaine, Seguret, Le Crestet, Suzette,etc), the Luberon (Isle-sur-la-Sorgue, Roussillon, Gordes, etc), Lourmarin, and Cucuron. There were plenty of markets with great produce, Roman ruins nearby (Vaison, Nimes, Arles, Orange, Pont du Gard, Pont Julien), and winery tours (we did Domain de Mourchon since it was in English). Something we really enjoyed was how quiet it was in the evening (especially after our time in Nice), plus we had a terrace with a great view. I'm sure there are equally wonderful hill towns in the Luberon that provide the same!
