"Hotel" quite bizarre difficult to be compared to an international standardized hotels.
Just a short corridor with about 30 room on a unique level, common with a restaurant.
The whole is situated at the 1st level up the main hall of the airport leading to the different gates.
Room especially noisy, + my rooms was totally blind, without windows... No Internet available...
Very bad choice, apparently the only rooms disponible directly inside Incheon International airport.
Avoid going there.
