We went for a couple getaway vacation, and in general, the stay was considerably satisfying. The day time staff speaks some English, well enough for communications at least, but the night time staff was absolutely impossible to communicate with as they only speak Korean. We arrived early in the morning and were able to check in immediately and even got an upgrade from Double VIP to Twin VIP, the room was pretty cozy but the bed was a bit stiff and the bath tub was a bit small. The rooms were sound proof but not the front doors, better to close the inner door as well if you'd like to contain your privacy and not let people in the corridors know what you are doing.
There were room cleaning services everyday, and on my third night, I returned to find my top (placed in my luggage) sprayed with some unknown chemicals and bleached with white spots on the surface. I complained to the reception the next morning and got compensation, my top was about USD 55 but the reception took a low exchange rate and only compensated USD 45 in Korean Won.
Apart from this, the hotel was not bad, quiet rooms and heated floors with lots of mirrors and systematic lighting decoration, pretty romantic if you're after a kinky atmosphere. There were computers in the room but Windows' in Korean so they're not that useful, the Wifi was strong so it was a bit deal and we just used our smart phones. However there was only one available socket in the room and we had to charge our devices one by one.
