Great little place very close (10-15 min stroll) to the lights and bustle of Shinjuku. 10 min walk to shin-okubo station. The place itself is across 3 floors with a bedroom, bathroom and separate toilet on the ground floor, kitchen and living on the first and two further bedrooms (one tatami) on the second floor. Steep stairs connect the floors as seems typical in Japan.
Host was very quick communicating. There is a convenience store 7/11 just a few steps away which was great.
All in all a good experience.
