Kei and Kotero are definetly the best guests ever ! Need anything ? They are ready to help you ! Lost in Tokyo ? They arrive to help you ? It´s your birthday ? They prepare a good meal, a delicious cake and also have presents for you ! They supply you with mobile phones and a wifi box to remain connected with the whole world. We are si glad to spend a few more days with them before our departure... The house is really clean, Kei is a wonderful woman and Kotaro is a real amazing man. They are really cute and helpful. We love you !!!!!!!!!!!!!!!!
