This is rather not a hotel, but a hostel, which has small single and double rooms with a private bathroom. The location is good: Myeongdong Street and other attractions are close, shops, cafes, two metro stations are nearby. There is a 24–hour minimarket on the ground floor of the hotel.
The rooms are tiny, with a bed inside, a small table, a refrigerator and a hairdryer. The bathroom has a shower without a curtain right above the toilet, and the water pours onto the floor. The view from the window is on the wall of the neighboring building, which is less than half a meter away. The room has high humidity and mosquitoes. But the linen is clean, there is a cooler with hot and cold water at the reception. It's quiet at night.
For your own money, $45 per night for a single room is quite acceptable.
