We stayed at Ritsuko's place for 3 nights and found it to be accurate in description. What we particularly like it for the location as it is very convenient to travel around Tokyo on the Marunouchi Line. On top of it, Araki-cho is just across the road where there are so many excellent food choices.
Our family of four adults love the space in Ritsuko's place which is great as we could use the dining and tatami room to relax and sleeping is on the second floor (2 rooms) with a toilet and living area.
