The housekeeper is staying at the first floor. At first, we feel uncomfortable but she is really helpfull and kind althought she can only speak Japanese. Before we check out, she gave us a pack of candy. However, this house is a three stories building. There is 1 room in the second floor, 2 rooms in the third room. Also, the only bathroom is only in the second floor and lavatory in the first floor. So please considerate your stay if you are planning to bring children/elder, also don't bring too much luggage unless you want to bring it upstairs
