The place is clean and looks like new, very faithful with the pictures, it's very well located but it's not what we expected: we thought we rent somebody's appartment but we realised it's a group of airbnb business and you have some tourists as neighbours.
However the district is really convenient (bar, restaurant, shops..) and very close from shinjuku (25 mns by walk).
As specified, the studio is really noisy (the highway is very close) and there are no real shutters on the windows so you are awake really early (5 AM during spring) when the sun rise up.
