Car Hire in Príncipe Real, Lisbon, Portugal

To prevent incurring extra charges, return the rental vehicle at the specified time. Always check the scheduled return time to avoid any surprises.

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

Select a pickup location that is convenient for you. Some rental companies offer locations within the airport for quick access, while others may require shuttle transportation.

Always keep your rental agreement, identification, and insurance information easily accessible during your rental period. This can help resolve any issues quickly.

Research toll roads on your travel route and familiarize yourself with their payment methods. Some rental agencies offer toll transponders for convenience.

If you have a specific vehicle model in mind, opt for rentals that assure the car type. This prevents surprises at pickup if a different vehicle is provided.

If you're traveling with pets, check the rental agency’s pet policy. Some companies allow pets, but additional fees or specific conditions may apply.

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.
