Stayed 4 nights in main building room. Majority of rooms have no normal window glass, feels like sleeping in a cave. Breakfast quality is one of the few positive aspects, but starts too late (7:30) to be at the lift on time. 15 minutes queuing for breakfast every day in a massive line. Onsen is a nice place. Unfortunately, showers are only available in the onsen, which is announced to be open only from noon to 9pm. Rooms are poorly sound proof between rooms and towards corridor. We will come back to Hokkaido but for sure not to this place.
