We booked the hotel weeks ago and requested for rooms on high floors but were assigned 2/F, which is a bit disappointed. The onsen is semi open air on roof, if only the washing area were enclosed, the experience would be a whole lot better.
Service is great. The hotel gave an eco-stay option in which we could receive some perks, such as beverages and ice-cream, in place of room cleaning services. The public bath is outdoors and not so pleasant when it is windy. Breakfast is simple and standard.
