The house is centrally located and approximately 5-10mins walk to subway station and groceries. Toilet and Shower on every floor is a big plus and one of the main reason we book the place. Honestly, at first, we find it hard to set up the heater for both the aircon and water (although Michi gave us instructions) and eventually we manage to figure it out but still, some rooms took enough time to be heated compare to another(1st floor for example and there is some leak in the Toilet). There is frequent power outage in the night which is a downside but only last for a few seconds but it is quite annoying sometimes if you are trying to turn on the aircon again and again and worst if you are asleep and you just notice it was not and its too cold. The house is located in a quiet neighboorhood and on a typical Japanese home you see in an anime. The house is best for a large group but it would be a bit crowded if you stay on 1 floor.
Few suggestions is that it would be nice that some facilities in the house should have at least an English translation on it at least for the important one (eg. Aircon Remote, Water heater, Toilet seat and etc.)
Overall it was a good stay and we will definitely stay again if we are to go back to Tokyo.
