Staying at Alessandro's place will make your trip do Florence better! He's really kind and hospitable. At his home you will be provide with everything: towels, slippers, earplugs, tea or coffee and more important - lot of tips, maps and wonderful stories about Florence. Location is about 2,5 km from centre, but next to guest house is a bus stop and you can get to all atractions in 15 minutes. I recommend Alessandro with all my heart!
