Definitely need pest control!! I caught half a dozen of bugs in the first 30 minutes of my stay and it was very very horrifying. Bugs kept coming in from windows despite that the staff had handed me a can of pesticides and I have already sprayed everywhere. Other than the bugs, the room decor was bit dated, and some wooden frames were broken. The windows and look out were very dirty and you dared not to open windows fearing some more bugs will get into the room. There was no air-conditioning but heat, and since it was not possible to open the window, the room was quite stuffed.
Other than the above, the room looked over the river valley and views were nice. Very good buffet dinner and also nice onsen. Staff tried their best to help though some of them needed Google translator to help. It was also in close proximity to nearby scenic spots. Overall good bargain but the "stay" was not particularly pleasant.
