The location is in a quiet area with lots of restaurants (though be aware many close by 6 pm).
Room is a good size, but there is no elevator and stairs to the second floor are quite steep - something to be aware of if you have mobility issues.
Matress on tatami floor was very firm, but comforter is warm and fluffy. There is no way to darken the windows, though, so light comes in throughout the night from a neighbouring sign, and it only gets brighter as the dawn starts.
There is also minimal/no sound priifing - we could hear every whisper in the hall, every door opening and clicking shut, and music from another room throughout the evening.
Private onsen time is nice, and the water is quite hot but comfortable (for us). The bathing area is clean. The massage chairs were nice to use after soaking in the onsen.
