The host Yuko is first of all amazingly responsive and goes out of her way to help you. Our luggage got delayed by days and Yuko helped us with coordinating its delivery and even was there to pick it up so we could enjoy the city. The airbnb is exactly as described and the location was the biggest benefit. It's in a nice quiet area but is so close to Shinjuku and other active districts that going out and seeing the city never felt restrictive.
Awesome place!
