This place is exactly as advertised - close to subway station, yet in a very quiet residential neighborhood. Somehow these two attributes coexisted. The host provides very clear instruction on how to check in - including sending a video clip showing how to navigate through the building main gate and operate the key lock box for the unit. There is also a grocery store that is only a three minute walk away, for those who would stay a little longer and want to get some variety for in-suite breakfast or snack.
I personally stayed at this place for the Tokyo Marathon. It is very walkable to the starting line at Tochōmae, and convenient enough coming back from Tokyo Station by taking the Marunouchi line.
