Wow! What to say.. I really had a great time at Savino's place! Definitely the best place I've ever been through AirBnB. The location is very good, the place is clean and the city of course is beautiful, but Savino is the one who really makes you feel at home in the city, and who gives you a real taste of Florentine life. He took me and the other guest out for dinner and drinks, but he also showed us around in the city, and introduced us to his (great) friends.
Like he mentioned in his profile, you arrive as a guest, but in just a few moment it feels like you've made a new friend!
