My wife and I love this apartment. A lot of care was taken in the design of the space and it is a very comfortable place to come "home" to after exploring the old city of Siena. The rooms are spacious and well furnished and the location is great - just a few minutes walk from Piazza di Compo, the Duomo, and just about anyplace else you would like to see in old city. Bring good walking shoes and you'll have a great time at Cassa Molli.
Sara was a great host and provided us with all the information we needed for the six day stay in Siena.
