Strongly recommended to book, if it's free. One of the best experiences of accomodation abroad for me. Close to city center (about 20 minutes to S.M.Novella) and very close to Esselunga (5 minutes). Big hall, two bathrooms, any kind of technical and kithen stuff (we didn't even know how to use some things). Seriously, any kind. Piero, the host, is very friendly and ready to help. I am already a bit jealous of his future guests.
