Being nearby Siena for 6 nights my wife and me wantend to rent a Vespa for one day on our own to be free to drive through the Chianti region. Googled and found sienabyvespa.com. Easy and quick reservation , ask for Carolina, she speaks English. Costs reasonably € 50 for one day per scooter (me driver and my wife passenger). Had a really fantastic day, we drove triangle Siena, Radda, Castelino and back to Siena, about 100km in total on secondary asphalt roads with a full tank. Before returning Vespa you need to fuel it up: only 4 liters, so economic too! I really recommend this company, friendly staff and easy, no strings attached.
