The house is tiny but same as description. It is clean & tidy& not so far from Hamamatsucho station (JR) and near Daimon station (10 minutes on foot). The building is old but the house is better because it was reformed.
My family of five could stay there without any problem but I think the maximum is five but not six.
Mr Kuniyoshi made response quickly. I met him when we checked out, he is very handsome and younger than I thought :))
