Affordable Kinosaki stay with onsen: This hotel offers great value for Kinosaki.
It has its own onsen that is shared between its guests in the morning. For extra privacy, you can even reserve it for private use in the evenings. The onsen itself is extremely simple and there is nothing special about it.
Important thing to note: my room didn't have a shower, which likely accounts for the lower price compared to other central Kinosaki hotels. Honestly, it didn't bother me one bit, as I was constantly exploring the amazing public onsens!
