Book Cheap AVIS Car Hire Deals in Sant Martí, Barcelona, Spain

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.

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.

Some companies may provide a complimentary tank of fuel with your rental. Understand the conditions, such as how much fuel you need to return with to avoid fees.

When selecting insurance, consider if it includes free excess coverage. This means you won’t have to pay a deductible in the event of damage, adding an extra layer of security.

If you're traveling with pets, confirm the rental company's pet policy before booking. Some companies allow pets but may have specific fees or restrictions, so it’s best to clarify in advance.

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

Before leaving the rental lot, check if the vehicle has essential emergency supplies, such as a spare tire, jack, and first aid kit.

When hiring a car, especially if you’re arriving in Sant Martí, Barcelona by flight, plan for extra time at pickup to accommodate any potential delays.
