In the female onsen I had a not so nice black-hair-experience, but that is due to some women not putting their hair up thinking it's fine to use it as their private bath, and probably not the ryokan's fault. And I went in there 10pm-ish, so probably everyone used it before me. Yet honestly, the cleaning standards were not as high as in other hotels I have been before - still good of course as it is Japan.
Again very friendly staff, like in most of Japan. The English wasn't too good but they showed us everything on maps - the ryokan is in the middle of everything you want to see in Nikko. The bus to lake chuzenji leaves just down the hill in front of the bridge, so all in all a pretty good location - but you should eat at the ryokan, it's a town that shuts down when the sun sets. They picked us up from the JR train station right after we called them with Skype (we had a pocked wifi), which was very convenient, and took us down again when we left. The outside onsen is simply beautiful.
