This is the best house if you want to stay in Tokyo, the host is excellent! She is Japanese and speak perfect english. The house is in a very nice and safe neighborhood. It is super close to the train station and you have supermarket that open til midnight, a 24 hrs restaurnat and at least two conenience stores 3 minutes away. Parking is not an issue even the house has no parking spot provided, I have a car and the parking space is always available when I back home at night.
I have been searching for the best airbnb for days until I found Nanako's house. Most of the house you can find in Japan has the kitchen/sitting room and bedroom upstair, it will be a huge problem if you have little child, eldery people or travel with lots of suitcases. Nanako's home has a huge room, sitting/dining area, kitchen and a full bathroom all on the ground floor. There is another full bathroom on the second floor which is rare in airbnb.
Location is perfect, just 20mins train ride direct to Shibuya.
