Apartment has a great bed, and Sei was very lovely. The heating is only for the bedroom so other parts of the house was still pretty cold and 11 minutes to shinjuku actually refers to the train ride only. But still the walk from the station to the apartment was interesting as it is through a small shopping area with many pachinko eatablishments. Still relatively close to Shinjuku, Shibuya and Harajuku, very convenient for JR lines.
