EVERYTHING was perfect (location, response, neighbourhood, etc) except for the wifi. I honestly advise people to bring their own portable wifi cause the house itself has a terrible signal and we were unable to use wifi smoothly when we're out in the city. (It restarts every 3 minutes.)
The room was huge (huge enough for housing in Tokyo). We had our suitcases wide open in the living room and we are still able to sit on the floor every morning for makeup.
The housing is very close to the station, with more than 3 convenient stores and a drug store (which has various kind of brands and stocks. There's no need to go to crowded MatsuKyo and Donki)
Kazumi and her neighbours are warm-hearted and friendly at all times and all means.
