Valeria's place was one of the best experiences I had on Airbnb. The studio is a little jewel of a home, decorated with paintings and beautiful antiques, set in a 17th century house overlooking a courtyard in a beautiful - but not too touristy - street a stone's throw from all that's worth seeing in Florence, with all the right shops and restaurants. Valeria's mother was a fantastic host, and gave me a lot of excellent advice about the city.
I'd definitely go back.
