Kei is really a great host that was supportive to us and our trip. He even made a recommendation for a nearby restaurant which we went to as soon as we arrived from airport - that first meal in Japan was great! The room itself is nice, futons are extremely cozy - makes you wanna stay in all day long ;) room is good for 2-3 people. Kitchen is well equipped, everything spotless clean.
Location is close to aoto station which itself is a bit far from the main areas of Tokyo so be prepared to travel a bit.
Overall great stay and we would recommend it to anyone!
