I-V 08:30 – 12:30 and 14:30 – 18:30
Key takeaway: Guerin (Salvador Caetano's Portuguese brand and Enterprise's franchisee in Portugal) operates two Aveiro touchpoints: the main downtown counter at Av. Dr. Lourenço Peixinho 213 and a secondary inside the CP train station (Loja 12). The downtown desk closes Saturday afternoon and all Sunday — the single biggest practical issue for tourists. Trustpilot scores guerin.pt at 2.6/5 across about 820 reviews, with damage-charge and cleaning-fee disputes as the dominant complaint pattern. Book through DiscoverCars with Full Coverage at €5/day to neutralise that pattern. Compact economy weekly rates run €150–€280 depending on season.

The “cleaning fee” is not insurable through any product — return the car broom-clean. DiscoverCars Full Coverage at €4–€7 per day refunds the excess and covers the SCDW gaps. Saving over €100 per week with broader protection.

About €220 in low season ($237), rising to €435 in August ($470). With DiscoverCars Full Coverage at €5/day, the all-in total is roughly €290 ($313).
Not quite. Guerin is a 100% Portuguese company in the Salvador Caetano Group and Enterprise Rent-A-Car's official franchisee in Portugal since 2012, so it runs the Enterprise, Alamo and National brands locally while keeping its own Guerin identity. Verified rentals via DiscoverCars score 8/10 — much better than the public Trustpilot picture.
Yes — Schengen, no checkpoint. Declare cross-border at booking to avoid a €30–€50 counter fee.
Not in Aveiro itself. The Aveiro touchpoints are the downtown counter and the CP train-station office, both city pickups. The nearest Guerin airport desk is at Porto Airport (OPO), about 70 km north, the practical fly-in option.
For the Guerin brand prices are usually similar either way, but a comparison site lets you check Guerin against every other Aveiro supplier in one search and often surfaces an all-inclusive rate with free cancellation. Compare first, then book whichever total is lowest.
