A friend had recommended Motor Inn for car rentals and I am very glad I stuck to contacting them.
In Santorini, you definitely need a car to get around- makes your life easier as well as you're free to roam about whenever you want.
We had a small issue of not being able to pay online. Despite not having paid, I rang Simos who helped us by ensuring the car would be delivered to the airport and payment could be made there and then saving us a trip to the office.
On the day, 7.30AM, Harry had met us, explained everything about the car and also gave us a map showing where we could visit and what places to avoid driving. This had been ever so helpful.
Motor Inn is very reliable and extremely responsive. Thank you Simos and Harry for helping us in Santorini.
I would highly recommend renting any services for this company.
