Nobu's home is located about fifteen minutes walk from the centre of Shibuya. Close enough to be convenient and just far enough away from the hustle and bustle of Tokyo so as to be quiet and calm. The house is minimalistic, yet has almost everything that you would need. There are a couple of supermarkets within walking distance, that have almost everything you would need.
Most things are located in intuitive places and it was easy to feel at home. The wooden stairs are a nice touch.
The heaters kept us warm, even during the coldest nights.
The only downside as others have mentioned is the two sets of stairs leading down to the house.
This is only an issue if you have an abundance of luggage which I don't recommend trying to cart around Tokyo anyway, or if you are elderly or have mobility issues.
Thanks to Nobu for letting us stay at her beautiful home.
