Great hotel. I may continue to use them in the future if they are available in my travel destination locales. Basic amenities are always available at the ground floor. Staff was friendly. Onsen was practical, but most importantly, it has an outdoor ONSEN.
I only wonder if the women's ONSEN is designed differently, as they don't switch the onsen's on different days.
If I did have a single complaint, it would be that they only provide (1) pillow per bed, and that the design of the pillow may not be for everyone. It's the type where the edges of the pillow have a thicker fluff anf firmness, and then towards the center of the pillow, there is a dip/concavity.
I struggled to find a comfortable pillow rotation for me. Again, that's my only personal issue with the stay.
