Podere Torre gave us a real sense of what it would be like to live in the countryside of Italy; it was relaxing, quite and extremely peaceful! Cecilia was such a lovely host - very sweet woman, who made us a delicious breakfast. (Our only wish is that we could have paid her to make us an authentic Italian meal for dinner. Oh, and that we actually made it home with her yummy olive oil! Make sure to buy some.)
We stayed in the farmhouse room with a private courtyard for just one night. For those who haven't been to Italy before (like us), 1-2 days in Greve is probably all you need - just because there is so much to experience in Italy.
One caution: make sure you have a good navigation system (or map) as we found ourselves down a dead-end dirt road at first. Also, the roads are narrow and some are one way. The Italian drivers are not forgiving and had us literally "back up" as if they had the ride-away.
Aside from that, a great experience overall!
