Found the apartment without any trouble and Enzo was there to greet us. Parked the motorbike in the street outside and never had any problems. The apartment and garden were perfect and the location was great for the trains, just 10 - 15 mins walk to Rifredi station . (Train to Siena €9.50 each way).
On departure after 5 nights, Enzo was back to see us off and have a chat. Very friendly chap, and his English was perfect.
When we come to Florence again, won't even bother to look elsewhere for somewhere to stay.
