Just Perfect!!　I give 21 points out of 20 possible :) .
The room is spacious, bright, clean, quiet and fashionable (with extra large wardrobes and attention to details).
The house is very cute, quiet and clean.
The place is convenient, located next to the station with a lot of shops, restaurants, bars etc.
Junya san and his father are veeery kind and nice people (Junya san helped to bring my luggage to the station!).
I felt like at home and plan to stay there during my next visit to Japan!!!
(I hope there will be available room for booking...)
