You cannot beat the location. Walking distance to shin-okubo station, as well as yamanote line. There is a conbini right around the corner, as well as a super market down the street and a coin laundry nearby as well.
If you enjoy walking, this is also a perfect location. Walking distance to Shinjuku and Shinjuku park.
The home itself is small but nice. They provide everything you could need during your stay.
