After 12 fantastic BnBs in Japan this one was terrible in every possible way. The listing boasted 100 m2 but it is actually less than 33 m2 (I measured the outside walls, one is 4.3m the other 3.8, there are 2 floors). The listing said there is a dining and living room (3LDK) but there aren't. Listing says oven, kitchen essentials like oil, salt - all of it missing. Kettle is broken, washlet doesn't work. Stairs are broken with nails sticking out, which was quite dangerous for our children. It's an old and ugly house, every window faces a wall from another house.
After I pointed out the issues (in particular the size) the host fell silent and never replied anymore.
Luckily AirBnB helped us to get a new place and paid a hotel for some nights that we couldn't move yet.
Don't book this place, unless they update their listings and more honestly show the modest place it is. Definitely not a place for a family.
