Han's a great host. He's very helpful and responsive, communication was super easy :).
The location is quite strategic, you only need to walk around 7 mins to the nearest station, and it is around 15 - 20 mins to get to shinjuku / shibuya area.
Details on the house manual including exact map, checked in procedures, and how to use some appliances are provided well.
The place is modern, the appliances are complete and working very well, the bathroom has its own heater which we loved.
It just has some dusty corners when we stayed there, and the sheets and blankets have some mild stains on it - which maybe because regular washing was not able to remove them.
But overall it was a pleasant stay, the place is very functional and modern.
