I would get the private onsen room if possible because of the convenience and the privacy. The public onsen was amazing if you don’t mind the nakedness and if your comfortable in your own skin.the rooms are quite and the area is less populated. I could hear my own thoughts and I didn’t like it at first but later got used to it and really enjoyed my stay. there’s a lot of eating option my group had a whole sushi bar to ourself. I would recommend staying again
