We are planning on spending one night in Siena and three in Pienza. Our objective in Pienza being to walk around the countryside; to Montepulciano, Bagni Vigno and one other. Since we are most of our time in Pienza I thought it would be fun to hire a driver to take us from Siena to Pienza and show us sights we will miss with our chosen itinerary. What do you think? How do I find a driver? There are four of us. Thanks.
