Our hotel was strategically located at the centre of transportation hub, with the express bus terminal linked to the extensive subway lines in the city.
The Koreans are terribly very punctual with their time. We were late by few seconds and the bus was gone. We tried chasing after the shuttle bus but it didn't stop. So, we went underground and traveled by subway trains, which were faster actually. Meanwhile, we managed to do some eye washing along the way and saw how colorful the place can be. A 20 minutes trip with one transfer from Express Bus station to Samseong station cost W1K, very cheap indeed.
