Just a 3 min walk from Takadanobaba (Yamate Line) and two train stops from Shinjuku station . My apartment is very convenient and has easy access to any central locations in Tokyo. There is Free Wifi . My home is clean and quiet . Up to two people can stay in my guest room. Please check House Manual of Airbnb when your booking is confirmed. I put some direction how to check in to my apartment (key arrangements etc.)
I really hope you will enjoy Tokyo.
