great site.
Customer be warned though: the refueling cost is INSANE. Do not return the car not fully fueled.
The car was great. What I feel appalled by is the street robbery price Sixt charges for a partial refuel. EUR4.6 per liter on diesel is not rational. The street price is less than EUR2/l. We were rushing to the airport and I trusted that refueling a bit would not generate such an insane surcharge. I do NOT recommend Sixt for this reason to anyone really.
