I had a great experience with Daisuke. It is very close to Haneda airport, and other places you may want to go. Actually, I haven't seen him in person, but everything was ready for us and comfortable.
One thing is that when Daisuke sent detailed pictures of the roads toward his house, I didn't pay enough attention because i presume that it wouldn't be difficult to find. However, you should pay attention to his email before travel!! It is not easy to find only with address. I got a lot of help from local neighbors. They were soooooo kind that they were willing to escort me to find his house.
