Easy to navigate and get to from the city (airport express from Dongzhimen station for 25rmb). Shuttles to gate are easy to navigate. However, the gates are very poorly marked and the arrows seem to point in very random directions, so make sure you give yourself enough time to wander aimlessly looking for your gate! Also, impossible to find stores selling basics (bottles of water, snacks, etc.) There is a duty free or high-end store every 5 feet, but no general store that would be appreciated before a 15 hour flight.
