I had the worst experience ever in Luton. They are not located at the airport and it takes a while to go by shuttle bus to a car park. They hold a 1250 Pounds deposit on the credit card which is still blocked 10 days after I handed the car back. I had set the limit of my card lower because of safety reasons, but there was no WIFI so I could have changed it and I had to take a high cost insurance with a lower deposit. I have booked a tank 25% full and empty on return. The tank was 75% full and they charged me 30 Pounds. I didn't go far and handed the car back half full with petrol. It took a very long time before I got the car in Luton because a couple in front of me had exactly the same problems. At the end it was a very time and money consuming experience, very stressful, lots of inconveniences and hassle. AVOID THIS COMPANY!
