An ordinary bus station. There is a small restaurant with tables where you can drink tea and buy snacks. While waiting for the bus to Antalya, I drank tea and charged my phone. I needed to get to him from the airport. The airport staff does not know anything and they will not answer this question. There are large buses to different cities at the exit from the airport. I was given a lift by a bus driver who was going to Marmaris for 110 liras to the bus station. With WiFi and comfort, I got there in 10 minutes. You can also take an Uber taxi, if you can connect the card.
