Nao and Julie are the most amazing hosts you could imagine. They are kind, always helpfull and fun to be around. Just as an example: They offered us coffee in the morning or a beer in the evening in their pub after we came home from our journey for the day.
If there was any question we had on mind they were happy to answer regardless if it was about our accommodation or cultural things.
In conclusion we really enjoyed our time with Nao and Julie and we would absolutly recommend visiting them if you want to go to Japan while having a central accommodation in Tokyo.
