This has a very nice onsen - super clean and great facilities, however the rest of the hotel lets it down... front desk hours are limited, decor is outdated, both in rooms and lobby, there are no private bathrooms (you must use the onsen if you want to shower), only way to get food is by ordering from local restaurants, which have limited hours.
An overhaul of the decor and the addition of some bathrooms/shower rooms with privacy would make a huge difference.
The window didn’t close in our room and would be unsafe for children due to the sheer drop to the river, with no barrier.
