Ken was a very nice host, very helpful, he quickly answered all our questions and did his best to provide us a proper stay. The flat was clean, their were some snacks and tea bags, a lot of towels and instructions for all the domestic appliances in English. We also used a portable WiFi router with 7gb traffic for two weeks in Tokyo.
The location is excellent, too: Meiji shrine and Yoyogi park across the road, Sangubashi and Yoyogi Hachiman stations of Odawara Odakyu line are 500 meters walk as well as Yoyogi Koen sta. To Shibuya, to Shinjuku, to Harajuku it takes about 25 minutes walking.
Very good for two people.
