Overall, the accommodation was okay as it as near the subway and for the price paid. For those that may want to consider this guesthouse, just for sharing, try not to stay in rooms located at level 4, as the pantry area is at level 4, and it will be quite noisy during breakfast time (8am - 10am). In addition, there is only staff from 8am to 11pm, and it was advised that guest will have to enter password to enter the building after 11pm (apparently that is not the case), which means anybody can actually access the building (might be a security issue even though there are cameras around). Furthermore, the room is rather cozy (small), don't really have much space to put much stuffs. Lastly, towels come in two sizes, small (slightly bigger than a floor mat) and big ones (normally runs out fast), and normally is 1 to 1 exchange.
Nonetheless, on the bright side, basic shower gears are provided. Staffs are rather approachable and friendly. TV channels are mostly in Korean, but surprisingly they do show Sports channel (EPL and UFC).
