The floor was not fully flat. The bed section was few inches higher causing step hazard for my old parents. The service overall was great and the cleanliness was excellent but I wished the outdoor bath had a cold water bath in addition to the regular hot springs. I didn't have dinner there but the breakfast was a-ok.
This was one of the highlights of our trip. The property was beautiful, and the rooms were amazing. I recommend doing half board and experiencing the provided dinner and breakfast. The location can be tricky if you plan on walking from Atami station, as it would take approximately 35 minutes and was mostly uphill. My regret was only booking to stay one night at this location.
