Hidy's house is literally the nicest AirBnB that I've ever stayed at. Granted, I've only stayed at a couple places so far, but after staying with Hidy, I'm probably going to be much less satisfied with the average AirBnB from here on out. Hidy's place is a mix between an IKEA display home and one of those super nice modern Japanese homes that you see in the movies. He also built like... 90% of the interior himself (including a hammock, that he sewed and installed himself, that has like three seating modes) because he's some kind of interior design genius. On top of that, he has more accessories than an Apple Store -- there's literally no power outlet that doesn't have a lightning cable and a micro-USB already plugged in an ready to receive your smartphone.
Anyways, enough about his place -- it's sick and that's that. Hidy also happens to be one of the friendliest guys ever, and speaks extremely fluent English. I asked him for a recommendation to a nearby Onsen and he spent like 20 minutes typing out three comprehensive reviews with links to other reviews... via Mobile. At like 10pm. He's a real busy dude (not surprised other people want/need his time, really) so he sometimes doesn't come home until late, but he's super responsive and would probably bring you dinner and a movie if you really asked him because he's that nice. Seriously, great guy.
TL;DR: Best house ever, Hidy is a boss, every other AirBnB home/owner needs to step up their game.
P.S. Hit me up if you ever come to California, Hidy!
