Book Cheap Firefly Car Hire Deals in Plaza de España, Madrid, Spain

Before you book, review the rental agreement for any hidden fees, such as airport surcharges, additional driver costs, or penalties for late returns. Awareness helps in budgeting appropriately.

Look up fuel prices in the area where you'll return the vehicle. Refueling at a local station is often more economical than paying rental company rates.

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.

If you're looking for extra comfort or features, ask about upgrade options at the rental counter. Often, discounted upgrades are available at pickup.

If you’re sharing driving duties, check the policies on additional drivers. Some companies charge extra fees, while others may allow it for free under certain conditions.

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

Ensure your rental agreement, ID, and insurance details are easily accessible throughout your rental period for quick access if needed.

If you plan to drive off-road, confirm with the rental agency whether it's permitted. Not all vehicles are suited for off-road conditions.
