I stayed at Fernando's flat on Borgo Pinti for about a week. It was fantastic! The apartment was clean, conveniently located near the Duomo, and had all the right amenities. Fernando was out of town but his terrific friend Maurizio let me in, (and was very kind about the fact that I arrived much later in the day than I originally intended). I plan to be back in Florence again soon, and I will definitely stay here again if it's available.
