I'd give Rinako-san's place 6 stars if I could. She went above and beyond to provide us not only a clean and comfy place to stay but plenty of refreshments and all the extra amenities like umbrellas and stationery that we didn't bring for the trip. Communication was always quick and to the point. Her apartment is right by the Shin-Okubo station, which helped a lot when we had to carry three travelers' worth of luggage on arrival date.
