Room was small as expected, but space used wisely. Bed was comfortable, though the pillows could have been thicker. As it stands, they are very thin - think of a thickness of a bathmat, and rather firm. Everything was spectacularly clean. Onsen / Public Bath was very nice - indoor and outdoor ones available - I estimate 8 total baths available. There are two family marts inside the hotel near the Onsen so you can rehydrate with your favorite beverage immediately after spending some times in the baths.
Check in and check out were a breeze, but I could see how a long line could form; we checked in late at 11 PM.
Location is great to get to local attractions. Highly recommend.
