Very neat, clean, and connected directly into railway station. Also, i love the scenery while the train leave airport (crossing river). Great experience. Love it.

Duty free shopping mall is very small though terminal shopping mall is very grace and big enough. Enjoy your time before immigration as long as possible.
Travelers beware! Security is ultra strict with liquids and they don't have ziploc bags so you will need to give up or go back to landslide shop to buy some. Very annoying!
