I absolutely love this place!
I would recommend getting the room with the private onsen in winter as it’s absolutely lovely.
The place is really nice and nestled on the side of a small Forrest.
The only downside is we had very noisey people above us, which they would continually stomp around until very late at night.
Very tiny room, barely had any space to put my luggage down, but its expected in Japan. Had to pay a lot of extra fees upon arrival. No facilities at all.
Enjoyed my stay here. The room was super clean and comfortable. And the place is walking distance from the metro. The only disadvantage is that there are no supermarkets nearby, only small stores.
