Great host, easy to communicate and to work with. The place is smaller than expected tho. You can definitely fit 4, but I would recommend just 2...Other then that, we did enjoy staying there. Got few restaurants and convenient stores just right around the corner. And only about 10min away from Haneda airport with public transit, very convenient. The check-in and check-out procedure is really easy. Definitely recommend this place if you plan to visit Tokyo.
