Room access was straightforward: they send a door code, and on arrival you swipe the handle to bring up the keypad and enter it. It worked fine, and the main entrance downstairs is accessible at all times. It's an easy place to sleep if you arrive late at ICN or have an early departure. The room was large and spotless, the bed was comfortable, and I didn't hear airport noise. If you miss the shuttle, you can walk from the airport train station in about 10 minutes, straight ahead the whole way.
