Great host who was very easy to communicate with and responded fast. Apartment is relatively big for Japanese standards. Location is very residential (as I wanted to) and gives local flair.
Flat however needs a few touches to make it bit more home like, especially that it is very dark, basically no day light in the living room and kitchen ( there is no window). So therefore I think overpriced.
I would stay again for 1-2 day trip but likely not for longer.
