From the Ankara Esenboğa Airport:
As soon as you arrive at Ankara Esenboga Airport, you can find regularly HAVAS buses (Airport Transfer Service-http://www.havas.net/en/) right behind the exit door to go to the main bus station terminal (ASTI) in the city centre (approximately 5 €, make sure that you've changed your money at the airport). It takes 35-40 minutes from airport to the last station, ASTI.
When you arrive at ASTI, take a taxi to the Turkish NA (it's between 10-14 Liras, 5-7 € and takes 5 minutes).
