Modern, clean AirBnB in a quiet less-touristy neighbourhood - but still close to the action in Shinjuku/Shibuya (local JR station is a 8-10 minute walk, followed by a short train ride).
Kaoru provided very clear instructions on checking-in and provided additional information on using the unit amenities, as well as a neighbourhood guide. She was also very responsive if a question came up.
A very pleasant experience overall.
