After a search of the many car rentals available in Santorini, we opted for Motor Inn since they offered us the best price. Simos was incredibly responsive and got back to us within few hours after all our emails, which made reservation and agreement on pick-up and drop-off locations easy and convenient. The whole process was very personal and we always felt like we were in good hands.
The car was delivered in time with a full tank to the pick up location at the port of Athinios by a friendly team from Motor Inn. We were given a Nissan Note instead of the VW UP that we initially chose. However, we were happy with the Nissan, since the price was still the same (the Nissan would technically be more expensive than the VW), and the car had everything we needed. The Nissan was clean and in a good condition (except that the clutch was not in the best shape anymore), and we enjoyed to get around with it on the island.
