I had a really pleasant stay at Takashi & Li's house "Miraie".
Unfortunately I couldn't spend much time with Takashi as he was off to Osaka most of my stay, but Li has been of great help and is a wonderful host.
Both have made their best for me to be able to check in early in the morning.
The house is within a short 10min walk to Osaki station which is well located in the "middle" between Shinjuku on the left hand side" of Yamanote Circle Line and Asakusa on the right side. It's has also a direct line to Odaiba, a popular location for leisure time.
i definitly recommend, and would not hesitate to book again if the occasion arises.
