Most hotels in Seoul were fully booked and we were very lucky to find a place. A friend then suggested to stay in the Biwon Hotel. Location is not too bad, but it's about two blocks from the nearest subway.
For only 60'000 Won you get a room with TV, Computer with Internet, DVD/CD Player and of course a clean room. We never made it to the breakfast because that's only from 7am to 10am.
Directions: Jongno 5(o)ga Station (Line 1, Exit 1) or Euljiro-4(sa)ga Station (Line 2 and 5, Exit 5). It's at the corner of Yulgongno and Changgyeonggungno. Look for the police station.
