Book Cheap Hertz Car Hire Deals in Sants-Montjuic, Barcelona, Spain

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.

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

Ensure you know whether your rental includes roadside assistance. This can be vital in case of breakdowns or emergencies during your rental period.

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.

Familiarize yourself with the fuel policy for your rental. A 'Full-to-Full' policy means returning the car with a full tank, while 'Same-to-Same' indicates you return it at the same fuel level. Full-to-Full is usually more economical.

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

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.

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