As others have mentioned, the main building is older, while the annex is newer. But, the main is remodeled and was comfortable enough. Nothing special, but it was directly adjacent the train station.
Breakfast was the best yet and staff were great and position is near the rail, but their rooms have outdated bathroom modules which have a high step in and out. These were new ideas 20 years ago but i was 20 yrs younger then and despite the warning sign designed to limit liability the had no grab bars which would have helped getting in and out. At 70 i consider myself reasonably agile but i still managed to pull my achilles tendon and will now have to reduce my activity over the last couple of weeks of my holiday. These bathrooms are not suitable for older tourists or thouse with restricted abilities.
Overall experience was more than decent. That being said, some less-common areas in the bathroom (e.g. the area beneath the sink was quite dirty, all black) and the television seems to be too small and old for the price tag I have paid compared to other hotels.
Front of the station, you won't miss it. Very good hot spring however, not running water. One thing I would say, noting around hotel and station. Difficult to find dinner place especially night time.
Great location as it is 1 min walk from the JR station. Nice staff!
But the room is small and the toilet facility is quite old that the ventilation is not functioning properly.
