I rented a 150cc quad for a week in Santorini. The service and the quad were great and the price was fair enough to let me choose Motorinn among different alternatives. They brought the quad directly to my hotel and I was not charged for this extra service, even if I was based in Karterados and they are located in Kamari. The quad was perfect for any road of the island, also in windy days. You'd better reserve in advance due to high demand in high season!
