DECAR - rent a car by haiamisa
We picked up the car, Renault Clio 1.4, at Decar office at the Ankara airport and first visited Bogazkale and after that drove to Cappadocia. After Cappadoccia we returned to Ankara and returned the car to Decar office at the airport even though we didn't fly from there, but it is an easier option than dealing with the complicated Ankara city traffic if renting the car from the city...But keep in mind: the petrol prices in Turkey are the highest of the world!
We rented the car via our travel agent in Israel and got it much cheaper than if we had booked it via Decar site.
