Does Florence have anything similar to ZipCar in the US? We'd like to rent a car for a single day (pick up in the morning, return in the evening), and the standard car rental locations are around $200.
Alternate suggestions are greatly appreciated!
We found Hertz to be cost-effective and doable for short-term rentals in Italy. I just checked there and a one-day rental for a Ford Focus "or similar" is around 82 euro, including taxes and mandatory insurance. The in-town pick-up locations seem to open at 8:30 am and close around 6, so you'd probably be returning the key to a drop box.
Here's a prior discussion here that may be of interest, regarding your pickup/dropoff locations in Florence: http://www.ricksteves.com/graffiti/helpline/index.cfm/rurl/topic/28422/big-problems-driving-rental-car-within-the-florence-historic-center-.html
I'm assuming they would be using the car for touring the countryside outside Florence for the day. They should confirm the pick-up location and make sure it is OUTSIDE the ZTL so they don't have any problems with that.
You can take a train or bus to Tuscany easily from Florence main station. I have done it and recom it highly. low cost and frequent.
