The mistake in most seven-day Italy plans is renting a car at the airport on day one and returning it on day seven. You then pay for parking in cities where the car is a liability, and you drive stretches the train covers faster. The fix is to split the week.
The structure
Days 1–2: Florence, no car. Fly in, take the tram from the airport, stay in the centre and walk. Florence is compact and driving in it is genuinely miserable.
Day 3: collect the car outside the centre. Pick up from a station or peripheral depot rather than the airport if the price is similar — you avoid navigating out through the ZTL cordon.
Days 3–6: the countryside. Siena, Val d'Orcia, Montepulciano, and over into Umbria for Orvieto and Assisi. This is where the car pays for itself several times over, because the good parts are the roads between the towns.
Day 7: drop the car, train to Rome. Return it in Orvieto or Arezzo and take the train in. Driving into Rome to hand back a car at Fiumicino on a departure morning is an unforced error.
The ZTL problem, which costs people hundreds
Almost every historic Italian town centre is a Zona a Traffico Limitato — a camera-enforced restricted zone. Drive in without a permit and you get a fine of 80 to 120 euros per entry. Multiple entries mean multiple fines, and they arrive months later via the rental company, which adds its own administration charge of 30 to 50 euros each.
Your GPS will route you straight through them. It does not reliably know about ZTLs.
The habit that prevents all of it: when approaching any old town, look for the blue 'P' car park signs on the ring road and park outside the walls. Italian towns are small — the walk in is five to ten minutes. If you see a round white sign with a red border reading Zona Traffico Limitato with active hours, do not pass it.
Hotels inside a ZTL can usually register your plate for temporary access, but you must give them the number in advance and confirm they have done it.
The roads actually worth driving
SR2 and the back roads through Val d'Orcia between San Quirico, Pienza and Montepulciano. The cypress-lined ridges are the postcard image of Tuscany and the driving is genuinely pleasant — narrow, slow, empty.
The SS222 Chiantigiana from Florence to Siena through the Chianti hills. Slower than the superstrada and the entire point of having a car.
The approach to Orvieto, which sits on a plateau above the plain and looks unreal from below. Park at the base and take the funicular.
Costs
| Item | Typical |
|---|---|
| Compact rental, 5 days | €180–320 |
| Fuel, ~600km | €75–95 |
| Autostrada tolls | €7–9 per 100km |
| Town car parks | €1.50–2.50/hour |
| One-way drop fee | €40–90 |
Fuel is expensive by North American standards at roughly 1.75 to 1.95 euros a litre. Diesel is usually a little cheaper and most rentals are diesel — check which before filling, since misfuelling is not covered by any insurance.
Rental practicalities
Book an automatic explicitly if you need one. Manual is the default in Italy and automatics are limited and cost more. Turning up hoping is how people end up not driving at all.
Bring the IDP. Non-EU licences legally require an International Driving Permit in Italy. Desks vary on asking; police do not, and an insurer can decline a claim without it.
Photograph the car thoroughly at pickup, all four corners plus wheels and windscreen. Italian rental damage disputes are common and photos with timestamps end them.
Take the smallest car you can live with. Tuscan lanes and medieval town car parks were not designed for an estate, and the difference between a Panda and a station wagon is the difference between an easy week and constant three-point turns.
