Satoru's house is a lovely four story spot just a little bit from Kinshicho Station and the beautiful Skytree. There's lots of rooms for everyone and the house is full of elements of traditional Japanese homes. There is also an incredible rooftop balcony where I spent a few days working when the weather was good, and having drinks with friends in the evening. The first floor is semi-separated from the rest of the apartment but linked with a hallway that has an extra WC.
Satoru met us at the house and made sure we knew all the ins and outs of the property. He is a receptive, communicative host and you can't go wrong with his space. It comfortably housed eleven of us- which in Tokyo is a feat in and of itself- i would give more than five stars if I could. I hope to stay there again!
