A great stay at Hisao place! Hisao is a very kind and nice host full of attentions. From the postcard he made on a homemade paper with a picture of us to the sandwiches his wife was preparing every morning, we really had a great moment.
The apartment is located in a quite residential area but only ten minutes walking from the yamanote which is very convenient.
It's an old house but the room was clean. If we had to name one improvement that is needed to our opinion, it would be the cleanliness of the bathroom and the toilets. Not the best of this place.
But we definitely recommend this place to stay in Tokyo! :-)
