We had a great stay in this quiet house situated close to mount Amiata.
The house: 2 bedrooms on the ground floor and a large living room with an open kitchen on the first floor. The house grant access to a large garden and permits to park the car. It's an healthy and practical house. Additionally the owners are very friendly.
Situation: From the house you have access directly by foot or by mountain bike to the trails around the mount Amiata (by taking the via della Montagna) which really worth a visit. You can also visit Santa Fiora and it's market or many other medieval villages around within a few minutes drive. Siena is only 1h15 from there, 1h30 for lake Trasimeno, and the beaches of Groseto only 1h away. In summary a great place to visit south Tuscany.
