Just 1 minute walk from subway station exit 1, airport bus (600) stops right next to hotel. Plenty of eateries around the area, very convenient. There is coin laundry in the basement, 3000won for washer and 3000 for dryer. It’s a very big machine and the dryer is so powerful, all my clothings were fully dried after 1 cycle and amazingly, not crinkle like the usual dryer.
