After a long flight, taking a bus from Istanbul Airport to our accommodation seemed too exhausting, and using a taxi felt like it would be stressful due to overcharging and haggling, so I booked in advance from Korea. I honestly expected a somewhat large SUV when I made the reservation, but a vehicle like a Staria or Carnival, converted like a limousine, showed up instead. At first, I was taken aback, but it seems this is quite common here. There were only two people in our party, and it was so spacious that we had a really comfortable ride. As soon as you exit through Gate 13, there are signs with the names of these companies on the left and right; just find the company you booked with, speak to them, and they will kindly guide you. The car arrived quickly, and the driving was very safe. The staff is also friendly, so try greeting them in Turkish! (Hello - Merhaba, Thank you - Teşekkür ederim). I also booked a vehicle for the trip back to the airport. If I get the chance, I will definitely use them again!! Oh, and as for the price, it is at least cheaper than a taxi, certainly not more expensive, in my personal opinion! I am not usually one to talk this much, but I am writing in detail so that others can try out this great service. Have a wonderful trip!
