Hiroko has a professional team assisting with that listing which is great! Communication, house manual, local tips all top notch! I would say this place is a great size for 3, a little right for 4 and uncomfortable with 5 (adults). We always stay in this shin-Okubo area when visiting Tokyo and Hiroko’s place is on a quite street close to the station (2 blocks) which is great! Very easy walk even with luggage.
