Book Cheap Sixt Car Hire Deals in Gràcia, Barcelona, Spain

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

Ask the rental agency about any specific local driving challenges or conditions. This can help you prepare for potential difficulties during your journey.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

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

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.

Prior to booking, check for any current promotional offers or discounts. Many rental agencies provide seasonal deals or early booking discounts.

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.

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.
