We really enjoyed our stay at Midori's place in Shinjuku! The apartment is in an elevator building about 10-15 minutes walk from Shinjuku Station, but there are also several other stations nearby to use as well. We were able to fit a family of four very comfortably and the apartment came with every amenity you could need. Check-in and communications were seamless via AirBnB and we never had any trouble during our stay. Midori provides detailed instructions on how to get to the apartment once you arrive and after that, it becomes very straight forward. I highly recommend!
