Kuniji’s place is excellent. Kita is a great place to stay for easy access to Tokyo, and the walk from the station to the house is very easy.
Inside, the place is really nice. Not at all cramped for three people, even using floor mats in the living room. This is one of the only Airbnb’s I’ve used in Japan where I never bumped my head! (I’m 193 cm/6’3”) Host is excellent with communication, thoughtful, and very accommodating. I would 100% recommend this space to anyone visiting Tokyo. It would make a perfect base for sightseeing and enjoying the city, with good nearby restaurants and shopping if you want to stay local.
