We booked a car two days before on the smartphone application; but unfortunately when we got there they did not have any car for us. There was a lady who left when she realized that they had a problem, letting the other worker there all alone. He admitted that he "forgot" to tell us that they did not have a car for us, when they definitely had our email address... Oh well, call before coming to pick up your car, and don't expect them to care.
