Noise may be a terrible problem for you. I heard a group downstairs (I think four floors down as I was on the 9th) chanting and banging the floor, perhaps 200 people, like a bar watching a soccer game. Unbelievable. And then there's the train that runs a stone's throw away. Stay on the front side or upper floors.
Hairs... Use a vacuum!!!
Although when booking the options for my room there was no mention of "Room without bed" or "tatami room," those were the only options I was given when I came to check in. It felt like an intentional bait-and-switch. I showed them my reservation saying "single or double bed room" and they just persisted until I knew it was faster to pay the money for an "upgrade" and leave an honest review. I must give the hotel only one star because the check-in error or their bad configuration on this website over a measly $30 and felt like just a two-bit scam. Their reply email was apologetic but did nothing to fix their error.
The rooms feel is designed for very Korean style close-knit family vacationing. If you want amenities or turn-key feeling, go somewhere else. This is not it. You will be best off if you really like cooking and traveling like a camper.
The resort is at the end of a quiet, somewhat abandoned feeling neighborhood (this is old coal country). Don't worry about safety, but it's not the place that you walk out the front door and have some things to do. Only about 20min walk to High1 nonetheless.
