I have just come back having hired a car for a week from Gordion Travel Agency.
What a delight they were. The car was waiting for us at the airport and the driver offered to drive us to our place in Akbuk. He said it was policy to make sure that the house was OK and that we were in the right place. I explained that I had friends who had checked the house and I knew the area well so dropped him back at the office.
The car was brand new and I just could not fault it or the service. I have used two other companied in Didim/Altinkum and would recomment Gordion without hesitation.
PS Muzaffer confirmed that anyone mentioning TFL gets a discount.
