We had a great stay at Ms Itoe's apartment. It was cosy, clean and very modern. The size was enough to fit the 5 of us comfortably. It has all the necessary amenities. It is in a quiet neighborhood and walking distance to the Shimbashi trajn station from where you can then go anywhere in Tokyo. It is also near Ginza and has a lot of convenience stores nearby. Ms Itoe's readily answers all our questions and inquiries.
This place is highly recommended. We will stay here again if we will come back to Tokyo.
