Stayed a double room in A NEW ANNEX building. Satisfied with the room condition, the location, and the reasonable price
(+): Good location, easy to get there, just 1-2 mins away from the Shinchon Metro station. Although the room is bit small, it has everything, and it is clean. There is a big grocery store at the first floor in the annex building. The new annex building is much nicer than the original building when it comes to security and circumstance.
(-): You might get a room (if you book a double room in the new building) with indoor window(not toward outside, but toward inside hallway), which the air is heavy due to lack of air circulation. It wasn't that cold, but that warm neither despite the heating system.
