Ryo provides detailed information for me to arrive easily and live at his place comfortably. I should mention that not many house owners would do such service for visitors. It is really not easy to find a location (even with an address) in Japan. His house is located in a very safe and quiet area and especially close to two train stations and grocery stores. That helps me live with ease.
If you want to visit Tokyo, Ryo's place is certainly the first place to choose!
