We stayed here for one night in april and it was wonderful. A bit further from the entrance than we expected but it was all worth It! Perfect location to explore Siena. Our room was clean and quite big as well. The breakfast was standard b&b breakfast. If you want something more, there are tons of bars, bakeries and fruit shops near by to buy your own breakfast. Had a great experience!!
One thing to note, parking is not that easy to find, and quite expensive if you want something near the b&b. Inside the walls of siena, you cant park. Finding parking just outside is possible but difficult. There is a parking lot just inside the walls but it is very expensive.
