The onsen bathing facilities were nicely designed.

The interior layout was a bit confusing, we never mastered the maze of hallways.

Ryokan with typical Japanese rooms. Several onsens available - public and private. That was nice. Location is in the middle of the forest. You have breakfast and dinner options available.

We kind of knew what we booked, so can't complain too much. Wanted to try a tradition Ryokan with an onsen in it. Not many options in the area available. In our opinion the hotel is just too expensive for what it is. And for us (as we are probably not used to it) the water in the onsen was too hot, so we couldn't really enjoy it.

"Entorno genial, habitacion amplia y onsen para rematar el dia"

Esta en un lugar rodeado de naturaleza, increible. Tiene onsen interior y exterior publicos e incluso privados que puedes utilizar tu solo. Si quieres hacer la Nakasendo trail esta muy bien porque tienen un bus que te llevan pero si vienes en coche como nosotros tienen un parking grande. Nosotros reservamos una habtacion japonesa que era super amplia y futon super comodo.

Todo estupendo. A lo mejor decir que si te molesta la luz al dormir, las ventanas dejan pasar un poco por la mañana. Yo lo solvente usando un antifaz.
