The room is old. Facilities is outdated like 20 year ago.
The private onsen is not really an onsen. They simply boil warm water for you only.
Mount Fuji and Lake Kawaguchi are surely a plus. The views surrounding are good. But i believe you could take a look of more options in the area.
The room is spacious and beautiful. A little bit old but clean and tidy. The private on sen is nice, running water and stable temperature. The tatami of living room is clean. The amenities provided are with good quality. The shuttle bus is on time and driver is helpful.
A point to note is that the room cleaning service swept away my white clothes on bed when they change the bedsheet, I would suggest they do not change the bedsheet if they see client’s personal stuff on bed, they can avoid accident happen again.
