Close to Isawa onsen station where you can take both buses, local & faster trains.
The hotel is a bit old school but nice, breakfast is a buffe which was pretty good, the onsen/shower & bathing was alright.
Most rooms higher up have a great view over the city.
There’s a 7/11 about 5/10 minutes from the hotel. Lots of vending machines at the 1st floor for water, beer, soda, coffee etc.
Barely an hour with bus from Kawaguchiko. 1 station from Kofu which you can take bus to shosenkyo (great nature experience and a ripe way to a beautiful mountain with awesome views), also walking distance to the Kawanakajima battle reenactment in oct/nov.
