If you want to stay like an ordinary Tokyo people, I would strongly recommend. It is not in the residential area, and so many bars and restaurants where local people, not tourists, love to have their 'get-together' meeting are around. Good location for Keio Mita Campus visitors. Very close to two subway stations.... both Narita and Haneda airports are accessible directly by subway without single transfer.
Nori is very delicate person to host the guests. Perfect amenities so you will find nice surprises whenever you open each drawers and closets. Beautiful and neat decorations rooms. Not recommendable for the family with very young children because of stiff stairway.
Really enjoyed the stay, and willingly come back when I visit Tokyo later.
