Our stay was great! Best Airbnb I've been to. The room was very comfortable (big for Tokyo standards), quiet and super clean. It's a 5 min walk to the Takadanobaba station on the JR Yamanote line. Very useful if you have the JR pass. The hosts are the kindest people I've met in my life and made our stay so pleasant.
I definitely recommend this place and I plan to stay here again on my next trip to Japan.
