I had the only private room and stayed 3 nights. The room is smaller than the size of a double bed. It has no ventilation once you close the door. The window does not open and is covered with insulation, so no outside light. It has ondol heating. The room itself is in an independant building of its own, standing in an inner courtyard, where are situated other small constructions: dorm rooms, a basic kitchen and 2 complete bathrooms. Mosquitoes would enter the room as I went in and out. Other patrons were not so respectful of the quiet hours after 22::00 and the noise carries. The street is pretty quiet but the neighborhood lively with the University crowd, restaurants, cafés, shopping, Sinchon subway station. Overall, it felt a bit like camping, and I was quite at ease in my little nest.
