We absolutely loved staying at Suginami, near Koenji Station. It had a close-together but spacious feel, it wasn't crammed & there was plenty of room for all 4 of us (all adult-sized people, one 6 foot 4). The following was great: cleanliness, instructions on how to use everything, comfortable mattresses, shower, computer games and Netflix, aircon in each room, very quiet even so close to the train and the theming and design touches. It was a very comfortable place to return to each day. The location was an unexpected bonus!! We had access to fresh-cooked, reasonably priced food, even quite late at night and only a minute from the front door. Several places had English menus and all the staff were friendly and accommodating. We spent most of one day just wandering around Koenji looking at shops and soaking up the vibe, which hadn't been the plan but we highly recommend you do make that part of your itinerary. So all up, we loved it and hope to stay again.
