Book Cheap Guerin Car Hire Deals in Arroios, Lisbon, Portugal

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

Note that some rental companies impose age restrictions or additional fees for drivers under 25. Always verify the age policy when booking.

When selecting insurance, consider whether it includes free excess coverage. Free excess means you won’t pay a deductible in case of damage, providing additional peace of mind. Compare options to find the best fit for your needs.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

Many rental firms prefer credit cards and may not accept debit cards for payment. If you're using a debit card, confirm the company's policies before making a reservation.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Some rentals have mileage limits, while others provide unlimited mileage. Review these policies carefully to avoid unexpected charges.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.
