Once you leave the freeway and take the exit Siena Ovest, continue to drive on the road called SS73, direction Massa Marittima-Monticiano. Cross the villages Costafabbri and Costalpino and about a kilometer from Costalpino you will find a curve with a little abandoned church on your right and a big building on your left.
Soon after the curve take the exit at your right towards Certano. After 100 meters get the descent on a white road on your right (Strada di Fornicchiaia).
Follow the road and stop at Villa Elena.
Somebody will be waiting for you at the Villa, ready to introduce you the whole property.
