The bath
What you’ll find
A cheap, no-frills community bathhouse (village welfare-center style) with sauna, cold bath and outdoor bath, dominated by local regulars and sometimes rowdy (karaoke, crowded sauna), with one dissenting reviewer claiming the water is chlorinated tap water rather than a real hot spring.
