Masami's apartment is very clean and the place is exactly the same as all photos shown. Very quiet neighbourhood, 3 supermarkets, medical shops, restaurants and drinking bar. Estimated 6 minutes walk to Hatagaya station which is 2 stations away from Shinjuku. If you are going to Tokyo station to take the Shinkansen, it will take 1 hour to reach after changing train at Shinjuku station. Thanks
