Place was very easy to find thanks to the welcome pack, and it was great to be able to walk to Shinjuku or just jump on the tube at Shin-okubo. Rather small apartment but perfect for two people if you travel light and/or are well organised/tidy. It was also very clean and the host left a few little gifts for our arrival. Mattress was on the harder side - but that's nothing in comparison to Japanese futtons we got to sleep on in traditional Japanese houses! :) The street is sometimes quiet sometimes lively. Although most nights were quiet, we did get woken up once in the middle of the night by some man shouting to himself for 30min. Overall perfect functional flat, would definitely recommend.
