Staying at Keiko's has been the most positive Airbnb experience I could imagine. Keiko greeted us at the door to let us upstairs, provided bread and snacks and tea, the house was immaculately clean, very close to Shinjuku and Shibuya, everything you could want in an Airbnb. The apartment is a little on the older side, but not restrictive in any way, and has been fitted out with all the amenities. Keiko is so friendly and responds almost immediately, and you can tell she puts a lot of thought into running the Airbnb. I'd definitely stay here again if I have the opportunity.
