I've stayed in a few Airbnbs in Tokyo, and this was my favourite. The apartment is large and spacious by Tokyo standards. I appreciated the presence of a washer-dryer with a good dryer function, as I have found this to be rare in Tokyo Airbnbs. There are lots of nice touches in the apartment, such as stickers on the washer-dryer to provide English translations of the controls, and numerous functions (such as Hulu) available through the TV. The apartment is also well-situated, with Higashi-Shinjuku station (A1 entrance) only a few minutes walk down the street, and plenty of amenities within walking distance. The apartment is looked after by a company, and all of my communication through Airbnb was with this company. I found them very helpful and extremely responsive; I even received a prompt response in the middle of the night when I booked this apartment on short-notice.
