Hertz

Hertz at Schiphol airport is neither better nor worse than the average rental car location at an airport. Service is usually fast and fairly friendly. Do sign-​up for the Hertz Gold plus membership (free) as it gives priority in the queue or if booked directly with Hertz you can just go straight and oick-​up the car.
Often easy to get upgraded for free as I have several times received a larger car than I paid for. Be aware that they try to sell the refueling option so you can return it and not have to fill the tank but that means you pay for a full tank no matter how much is left so i always prefer to refill it myself.
Have tried most of the rental car companies at Schiphol and Hertz is among the better (speed, friendliness and chance of upgrade) and usually decide based on rental cost.

Avoid this branch at all costs. They keep their prices low and competitive but come back with exorbitant fees after the fact. Terrible experience, would never rent with them again.
