We stayed there for one night during a ski trip.
The best thing about this place is the location, since it's really close to the lift and the rental shop.
The staff was polite, and the food was OK (mainly regular Japanese food).
However, they should really work more on the cleaning, especially in the common areas. The entrance hall had a weird smell and the public bath's floor and walls really needed some scrubbing (fortunately the bathroom inside the room was gone).
In general, it's not a bad place for the price, but I'd think twice before going there again.
