Kaen's place is as advertised. The location is fantastic and close to two rail lines with easy access to the rest of Tokyo. Shinjuku, Yoyogi and Harajuku are a pleasant walk if desired.
The room itself was clean and spacious, and check in was exceptionally ease. Kaen is super responsive and helpful, we never had any trouble reaching her and she always responded to any of our inquiries in a timely manner. We'd happily stay here again :)
