Great budget hotel about 20 minutes away from Gotemba Station on walk. (Taxi ride is about 5 min for about 900 yen if I recall).
We had a nice room vith view on Mt. Fuji, which we climbed the day after our first night. Bed were really comfortable, breakfast was ok, earlier enough so we could catch the first bus to Mt Fuji. Similar to a Best Wertern, Quality inn, Holiday inn, etc.
For about 3900 yen a night per person, including all commodities such as AC, private bathroom, comfortable bed, no curfew, breakfast... two thumbs up!
