Had a great and affordable stay. The staff were extremely accommodating even though I don't speak Japanese. They spoke slowly, provided maps and instructions in English, and couldn't have been more friendly and professional.
The location is beautiful and nearby Koriyama, Lake inawashiro, and Mt. Bandai.
The onsen is split between outdoor and open-air, was very clean and relaxing.
The rooms were super comfortable and had tons of space.
They also have a great dinner and breakfast, and provide sake.
