Shins' place is perfect to relax after the hustle and bustle of the surrounding cities. The house was very cozy and inviting, once you're used to the "stairs" they no longer seem like an issue. Shin made me feel very welcome and was always up for a chat! The bathroom is rather small but as are most in Japan. The rooftop was a brilliant surprise and had the perfect view for the sunset. Easy access to Hatagaya station makes travel to and from shinkjuku etc incredibly easy.
Definitely will be staying here again the next time I am in Japan.
