The staff is very friendly and kind. They were absolutely the best part of the stay. The street this hotel is down is a block a way from the more fashionable streets near by, however that does keep things a bit quieter in the evenings. I stayed in a nicer place in Seoul for the same money, so I don't feel I got a great value. The breakfast was nice, but not a lot of options--they make you a sandwich each morning or something to do with bread and then you have choices between yogurts, cereals, fruits, milk, and toast. Juice, coffee, and tea are also offered. The laundry currently costs 2000 KRW for a wash that takes 60 to 90 minutes and a dry that costs 5000 KRW for an estimated 200 minutes to 4 hours. They provide drying racks, but the room was so humid my clothes didn't dry properly and a had to take a hair dryer to them (still not good enough though).
Overall, if you are used to hostels, you will be fine with this choice. I'd personally consider a business hotel a step up from here.
