If you plan to have someone else drive, check if the rental company permits a second driver and whether there are extra fees involved. Some may offer free additional drivers under specific conditions.

Before hiring a car in São Nicolau, Porto, carefully review the rental conditions from suppliers like AVIS. Pay attention to details on payment card requirements, deposits, cross-border travel policies, and driving licence requirements to avoid any surprises.
