Truly a worthwhile experience!
We thoroughly enjoyed our stay at Noa's accommodation. The house is located at a peaceful neighbourhood in Honancho, which has proximity to key areas of Japan, for e.g. Shinjuku, Shinbuya, etc. The local subway rail line is walking distance (5 minutes) from the house. However, please bear in mind, the line is not supported by JR pass and it would cost around 170 yen to reach (in 10-15 minutes) Shinjuku, from where you can cover length and breadth of Japan using your JR pass. The neighbourhood has good number of restaurants and convenience stores nearby.
The room we got was a traditional tatami (Japanese styled) room, enough to accommodate 2 people. Noa and Lina ensured the cleanliness of the room before our arrival. The room is also equipped with an air conditioner/heater. The bathroom and the toilet are located in the basement, and you have to pass the living room while making your way. However, I believe that is a normal style of architecture discovered in Japanese homes. We were handed over a spare set of keys so that we can move in/out at our convenience. Noa also gave us the pocket wifi which we made full use of, during our trip.
We were well connected with Noa throughout our trip, and would like to extend our gratitude to him for responding to our queries promptly.
I would highly recommend this place to anyone visiting Tokyo.
