Very nice staff. However, there was black mold in the bathroom, the entire place is closed from 10am-3pm, it's hard to find the staff even during "open" hours, and it's far from the train station. It is very close to all of the 7 Hells and some of the best onsen in Japan.
Great location if you’re visiting Hyotan Onsen etc.
En-suite showers are a little small, and the hot water isn’t very hot (which is strange for a hotel with a hot spring). Not a big deal though because you could just go downstairs and shower in the on site hot spring.
The Rooms had a great view of the city and the sea.
Overall pretty decent place.
