We stayed here in early november and it wasn't that cold. however, when we entered our room, it was super warm and stuffy so we tried to turn on the air conditioning and it wasn't working -- turns out in fall/winter, hotel turns off the main air conditioning system so even if we try to turn the AC on in our room, it won't. this was a big no for us since we traveled with our soon-to-be 1 year old boy who is very sensitive to being warm (he would cry and won't sleep if it's a little hot).
also, the hotel charged us 33,000won per night for bassinet so we it was a total of 99,000won for total added to our bill. It's unfortunate that they charge for the bassinet whilst most hotels we stayed at did it for free. Even the bassinet was for a small child so my boy was getting out of his bed at night.
anyways, this hotel was clean and all but need some work in amenities and hotel facility care.
