The location of his house is good. Only 5 minutes walk from station, and the station is on Hibiya Line which is perfect if you want to go to Ginza, Roppongi, Ueno, and even Nakameguro. Because hibiya line covers it all. You can even see tokyo sky tree on the way to his home.
The room is so spacious, and nice. It fits 7 people perfectly. And i love the 3rd floor space. The 2 rooms and the bathroom is tidy and comfortable.
We are 10 people, consists with 8 adults and 2 children. When we arrived and returned to Narita airport, Sangjo and his friends picked us up (with a very reasonable price) so we dont have to catch and transfer train to his house.
Definitely will come back again if i stay in Tokyo. Terima kasih, Sangjo-San!
