I booked 2 rooms for myself and family.
The staff are friendly and helpful, and the rooms have very large TV's and a PC in them. The hotel is smoke-free but my room definitely had a smoker in it previously.
Check-in time is 5:00pm (ugh), but you can drop off your bags earlier if needed.
The hotel is totally Korean - staff did not speak any English and all the instructions in the rooms were in Korean.
You take your shoes off in the entry-way and wear slippers provided. The room has one window, tall but only about 2 feet wide) which has no curtain but a wooden "door" to open or close it.
The lights, air-conditioning, and TV are all operated from the same remote control (everything in Korean).
There was a sign in the restroom saying not to put toilet paper in the toilet because it could clog it, and instead put it in a small trash can provided. Hmmm ... make of that you will. Unfortunate for the hotel I suppose if they have guests who can't read Korean.
Wi-fi is free but unsecure ... apparently there are several room numbers with wi-fi assigned to them, and you just pick the one with the strongest signal.
So the rooms are okay, nice big modern TV and PC in them, but a tad dark even with the window door opened.
