We stayed at Shi's place at the end of September. It was much hotter than we expected but fortunately the air conditioning all worked very well and quickly. Additionally Shi left notes for how to use all the remotes as all the buttons were in Japanese.
The house was just as pictured and extremely clean. There were helpful instructions all over. Especially helpful for us tourist who weren't used to turning on the water heater.
Shi also sent instructions on how to find the house that were very helpful. We got there late so it was a bit dark but it was still easy to find.
One great thing is that Shi has left pamphlets and books of sites to see around Tokyo in the living room. They were very helpful to browse as we were resting.
Thanks Shi!
