I am originally from Tokyo and used to live in Yotsuya so I am well accustomed to the area but Ben san was very helpful and gave me detailed information on how to get to the Airbnb and information about the area. I would be very comfortable navigating the area even if I knew nothing about it.
The house was well kept and overall clean. However I felt that the sheets and bedding needed more maintaining.
All the necessary amenities were supplied and made our long stay comfortable. Overall I would recommend this place.
