Satisfied

Upgraded from EQA to EQS for only 15 euros a day, but an additional service fee was charged without prior notice.

It was average. The process took quite a long time, and at the end, they said the pickup time was 15 minutes early, requiring an extra day's charge (early pickup and return were not allowed). They persistently pushed insurance; you need to be firm in declining. The counter only handled key collection, with no staff accompanying you to the car, which means if there's an issue with the car, you have to walk back a long way to find them.

Great service, even though it's not my first time renting, they still explained the details carefully

Ended up with a Mazda 6. An amazing car. All sorts of extras that made driving easy.

Was a great experience.
