We were a family with 5 people (3 teens + parents) and the apartment had enough space for that (even if one place is used for both living room and room with a thin Japanese futon). Really very clean, special attentions for welcoming (tea, coffee, sweets, cakes, mineral water in fridge); Location is ideally next to Shinjuku station and the Shinjuku park by walk or with subway, but in a quiet area ! Full guide provided for the apartment and recommended addresses around the area for shopping and food. Easy self check in and check out. Host available at anytime if needed. The right choice for an apartment in the city center. Many thanks.
