And - personal preference - I like rural ryokan with an old world feel. I think that spending an evening at a historic inn in a little town like this and is "must do" but YMMV -

jib71. Shoot for higher end and if you are worried about communal bathing find one with private facilities or a reserved private time. I've stayed in minshuku ryokans (low-end) and the famed Hiiragiya in Kyoto, and enjoy them all for the cultural experience (of course Hiiragiya was by far the best experience), but high-end offers the most cultural touchpoints with the least hassle in terms of creature comforts. Try it for one night and see how it goes.
