Picking up the car was quite a hassle. The sedan I booked was not available, so they gave me a hatchback instead. I had to wait from 2:30 AM to 5:00 AM to finally get the car. The company's counter is opposite Gate 4 at the International Terminal, but the staff sleep at night. Sometimes they don't answer the phone; you need to knock on the door behind the counter to wake them up. Don't follow the map to the Domestic Terminal; its counter closes at 7 PM. Also, the pick-up is by the roadside 7-11 outside the International Terminal. If no one is there, don't wait; go directly to the counter and ask them to call someone out. The 3 stars come from the return service - dropping the car at the airport only took 5 minutes. Additionally, the deposit was refunded quickly, within a week.
