Everything went smoothly when picking up the car in Göreme, but returning the car at Izmir airport was a nightmare! Our flight was at 4:15 PM, we arrived at the airport at 1 PM, but couldn't find the return location and couldn't reach anyone on the phone. I had to run to the airport by myself to ask for help, running from the international terminal to the domestic terminal, struggling with the language barrier and fearing we'd miss our flight. After finally finding the Avis counter, I expected someone to help guide us back to our car, but the staff were too busy and told me to go find it myself. It took two hours in total, and we finally returned the car after 3 PM. Luckily, the flight was delayed, otherwise we would have missed it! I ended up crying in the airport parking lot out of frustration!
