Everything went smoothly with the rental and return. There are two issues to note: 1. The map indication for the Budget rental location in Madrid is incorrect. There is no rental point in the city center, only at the train station. Fortunately, I confirmed this a day in advance. Also, during the rental process, the car rental staff will inform you that the driving license translation provided by QEEQ is not legal in Spain. They can still rent to you, but if any issues arise, the police will treat it as driving without a license.

Tried to charge me for fuel but had to show them it was Full to Full. Then gave me a van instead of a car and said they didnt have anything else. Was asked to come back next day and picked up a better car. Hassle but worth it in the end

Car was great, they gave us a bigger car, small SUV. Paid more in tolls in Portugal as they count small SUV's as class 2, which means 3 times class 1, regular sedan! Also there was an additional airport charge.

Worked well for us, overall... will use again!

budget / avis believed car was not full to fill fuel policy. Had to persist and show the print out. A little frustrating. Also car needed a service and had a fault gearstick.
