Sixt is the premium in-terminal option at Porto Airport: a service counter on level zero of arrivals (turn right toward the car-rental area), a newer fleet, and DiscoverCars rates it 8/10. You pay for the convenience and the cars – Sixt is among the pricier names at OPO, and its Portuguese Trustpilot score is low – with recurring notes about insurance clarity and extra charges. Good for travellers who want a modern car and a walk-to-counter experience, provided you understand exactly what your insurance covers before signing.

Sixt has an in-terminal counter on level zero in the arrivals area – after the gates, turn right toward the car-rental counters and the Sixt desk is among them. No long shuttle; cars are in the airport car-rental area.
DiscoverCars 8/10, in-terminal, modern cars. The trade-offs are price and insurance clarity – understand what your booked cover includes, because Sixt sells its own full coverage separately and a third-party policy may not waive the excess at the desk.
DiscoverCars 8/10 like Sixt, usually cheaper, with multiple Excellent Service Awards at Porto. A strong alternative if price matters.
Lower headline prices but bigger deposits and refund delays. Sixt is far smoother if your budget allows.

This is the key Sixt point. Its rate includes CDW with an excess; Sixt sells full coverage separately, and complaints note that a third-party policy bought via a booking site may not waive the excess at the desk – meaning you could still be liable in an accident unless you take Sixt’s cover. Decide before you travel: either buy stand-alone excess insurance and accept the hold, or budget for Sixt’s full coverage.
The A28 coastal motorway north to Viana do Castelo is toll-free since 2025 (with the A24/A25). The A1 (south to Aveiro/Coimbra/Lisbon), A3 (north to Braga and Spain) and parts of the A4 remain tolled, mostly electronic. With a rental, take the company’s Via Verde transponder (small daily fee) or expect tolls plus a €25–50 admin fee billed afterwards. Fuel in May 2026 is about €1.95/L petrol and ~€2.00/L diesel; supermarket pumps cheapest. Return the car full.
If yes, Sixt delivers; if not, Guerin is cheaper at the same 8/10.
Know exactly what waives the excess to avoid the most common Sixt dispute.
The Douro Valley, the toll-free A28 coast and Braga/Guimarães are all easy drives. Porto’s centre is walkable, so collecting the car on departure day is common.
Yes – the Sixt counter is on level zero in arrivals; after the gates turn right toward the car-rental area. Cars are in the airport car-rental zone, so no long shuttle.
It is among the pricier options, reflecting the newer fleet and in-terminal counter. Guerin shares the same 8/10 DiscoverCars rating for usually less.
Insurance clarity: Sixt sells full coverage separately, and a third-party policy bought elsewhere may not waive the excess at the desk. Confirm exactly what covers you before signing.
Stand-alone excess insurance (€4–7/day) is cheaper and refunds your excess directly, but Sixt will still block the excess and you carry the risk in an accident unless you take their cover. Choose deliberately.
The A28 north is toll-free since 2025; the A1 and A3 are tolled (electronic), with a €25–50 admin fee on rentals. Take the Via Verde device if offered.
