Joan is really friendly, we arrived supper later around 11:30pm, but she also came out to pick up us. And she and her son also helped us to bring our luggages upstairs. She also introduced some wonderful place to is, you can ask for help whenever you want, she is so lovely.
The room is super clean and she prepared everything for us, such a satisfied experience with AIRBNB. She prepared extra heater and there was a small fridge in there which was so convenient!
If we go to Tokyo again, we would like to live in her house again!
