Pros: 1. The front desk reception was smooth, the order was clear, and the process was not cumbersome. 2. The car was in good condition, spacious, and both the interior and trunk were clean. 3. The staff were very polite and their English was sufficient to solve general problems. Cons: 1. The car did not come with a full tank of gas. Due to being in a hurry, I didn't check this and the staff didn't remind me. They didn't adjust the rental cost either. I ran out of gas after less than 100 kilometers, but fortunately noticed the gauge on the way back. I spent 550 RMB to fill it up but only got 100 RMB of the rental fee refunded because I was rushing to catch a flight and couldn't argue about it. 2. This time I didn't pick up the car at the airport, but I will next time. However, Avis's desk at Gimpo Airport is at the domestic arrivals exit, while we were at the international arrivals exit, which is quite a distance away. I'm not sure how to resolve this issue, can there be a pickup service?
