Grapehouse koenji was definitely one of the best places I've stayed in Tokyo, if not THE best :-) the interior of the house is lovely, the room (including bed) is super comfy and the hosts are so kind!! It's a really personal atmosphere in this house which makes it feel really homelike. So all in all I would have loved to stay longer but unfortunately it was already fully booked. If I ever come back to Tokyo, I'll definitely come here again!
