My stay at Grapehouse Koenji was not good, was excellent! Sonae and Kazuko were great hosts, very helpfull and kind. The place is very clean and well-organised. The location is perfect, Koenji is a JR station and it's easy to go to one of the main stations (Shinjuku - hub for several JR and metro lines). I trully recommend Grapehouse Koenji! Arigatou gozaimashita!
