Very functional, clean, modern house. Kitchen good. 2 toilets, One on L2 next to living and one on L3 next to sleeping. Washing machine and bathroom all easy to use. Plenty of towels. The location is superb, lovely street, a short walk from Higashi-Nagano station and a 7-11 convenience store that we used a lot. Only 2 stops to Shinjuku so incredibly convenient. We had a family of 4. 2 adults and 2 kids (although one of them going on 17 so more like an adult). The sleeping space upstairs caters for this perfectly with parents in 1 room and the kids in the next room. To set realistic expectations, it is not a big place. Just enough space in the living area and kitchen and bedrooms for 4 comfortably. If the place was used strictly for sleeping and you did most things on the outside, then you could fit in more, but it would be a bit tight. This is not a criticism though as all properties this close to the centre of Tokyo will likely be fairly compact. It is natural for Tokyo.
