Jay's place was great. It's in a great location very close to Higashi-Shinjuku station, and tons of shops and restaurants in the vicinity. The apartment is fairly small and narrow, but that's typical for Tokyo, and the apartment is arranged in a very thoughtful way so that you have everything you need and never feel cramped. The bed was very comfortable and everything (WiFi, AC, etc.) worked as promised. Jay was also very helpful in helping me retrieve a laptop charger that I left behind. Would definitely recommend staying here!
