A cosy lived-in apartment at an excellent location just a stone's throw from Shin Okubo station on the JR Yamanote line, just one stop away from Shinjuku and with many convenience stores and restaurants nearby. We travelled as a family of four and the apartment was much bigger than we expected. Take note that Shin Okubo station doesn't have an elevator, so you might want to alight at Okubo which is 700m further if you're travelling with a family and have many suitcases like we did. For the excellent location the slight downside is hearing the subway noise rumbling till late at night, which I imagine is par for the course for many people who live in Tokyo, but might not be the best choice for light sleepers. The host was very responsive and we appreciated the free pocket Wifi which came in very handy.
