Best AirBnB of the holiday, hands down. Plenty of space compared to most in Japan, really nice furnishings, and excellent host. Futons were comfy, bathroom was well-equipped, and laundry machine was very easy to use. Even has a sofa!
Location provides excellent access to two subway lines with a short walk to the JR lines and rest of Shinjuku. Nowhere in all of Tokyo took more than 30-40 mins to get to, most places only half of that time.
I actually had a really nice evening staying in one night to read instead of going out. Would recommend.
