Ken's place is exactly as described. We are a family of 5 (2 adults and 3 kids) and had plenty of room. Interior is bright and the place does not feel cramped.
Location is awesome. It is a short walk to a major JR station, Metro line, Supermarket/Grocery stores, restaurants and multiple convenience stores.
Would definitely stay here again. Only slight downside was not dealing with Ken as he uses Zen's to manage his apartment.
