We did have mixed feelings about this place, so here is a short pro/cons review:
PRO:
You get to sleep in a nice japanese house for a quite cheap price. The tatami beds are really comfy. It's also very easy to access the house, as you only need a code: no key here. The instructions to get to the place were really precise and super helpful!
Hiro was even very nice to allow us to check-in a little bit earlier, and this was greatly appreciated.
CONS:
We noticed a bad humidity smell in the bathroom & kitchen. Also, note that the tatami smell might be also a problem for you, but opening windows for a few minutes should fix this issue. Also, note that the house is quite small, compared to what you might think looking at the pictures. You know, wide-angles photos tend to make rooms seem bigger... If you are a tall person, you might have to be extra careful here. Last thing, most windows open on the wall of another building. So don't expect any kind of view here. The only room that opens on the "outside world" has a small but very dirty balcony.
TLDR;
A quite cheap place that would deserve some work to stand out. It's sad, because the house could be much more beautiful.
