The hotel is located at nowhere, so there is not entertainment if you wanna go out. Outdoor hot spring is facing the bay, very very nice~and the dinner is perfectly great with the price.
However, the downside is the rooms are small and old, toilet smells and can't stand to stay in it. Also, towers in rooms are not satisfactory too. I would only go for hot spring and dinner, but don't recommend to stay for the night.
