Kan was extremely communicative during our entire process. His home is clean and thoughtfully designed. The neighborhood where the house is located is also very quiet, and it was lovely to spend the day in the hustle and bustle of Tokyo and "escape" to the serenity of his house at the end of the day.
Really, there's only one thing worth mentioning: It's a bit small for two people and appears to be Kan's primary residence, which means he still has many of his personal items and food stuffs in there, exacerbating the amount of available room for you to use.
But generally we enjoyed our stay there.
