My husband and I spent Christmas week in Casa di Alice, a lovely two bedroom apartment in the small hill town of Castelnuovo dell'Abbate. The town is beautiful and it made the perfect base for day trips to Siena, Montepulciano, Pienza, Montalcino and Arezzo. We loved our time here; the residents are lovely, friendly and helpful, although most are not English speakers.
Things to know: The town is very small; there are two small restaurants but at least in the off season, they have limited hours. There is a small coffee/wine bar just steps from the apartment with lovely wine selections and a small grocery store that stocks the basics. The town is very hilly and parking is down hill from the apartment. We didn't find it a problem, but those with mobility challenges would. Also, most of the wineries in the area are closed this time of year.
