Han River Guesthouse is an awesome guesthouse. The managers are all very friendly and helpful. The room is very nice and decorated nicely. I got a pinky room and it was upgraded from double bed into triple bed without additional charges. It provides a nice kitchen with sufficient utensils so I could cook or heat our foods. The guesthouse is located in the high place in Mapo area, so at night you can enjoy beautiful Mapo scenery from the rooftop.
