Incredible value. I stayed 3 nights in Holoholo Inn. I was a bit confused upon arriving at the Old Japanese Schoolhouse, but the hostel is right next door. Incredibly convenient base for exploring Volcanoes National Park. I arrived in the afternoon and Satoshi was there working on something in the yard (he seems to always be tinkering to try and maintain or improve the space). The building is quite beautiful! Lots of natural light especially in the kitchen/dining area. Some nice touches like tea, which you'll need because it gets cold in the winter! Bring some long sleeves to sleep in as it is cold at night. Bring your own soap and shampoo. Towel is provided. Laundry and detergent is available, and there's an extractor to reduce drying time! I'd never even heard of that before, but it sure worked well. There's no staff around on the premise at night, but this wasn't an issue for me. Overall, it's a super cozy and beautiful house, and a steal for what you pay. Definitely recommend.
