The house is located in a quiet local and convenient residential community where just it take around 5 minutes by walk from two metro stations, Yotsuya-sanchome Station 四谷三丁目駅 of Marunouchi Line 丸ノ内線 or Akebonobashi Station 曙橋駅 of Toei Shinjuku Line 新宿線. There are almost no noisy crowd or tourist as center Shinjuku, which is good to feel real Japanese life if you want, but also it is very easy for us to go to major shopping centers and sight spots by metro.
It looks newly decorated. The host makes the house be convenient and comfortable for us to stay just like at own home daily living, not an inn like other Airbnbs. We have two adults and one 3-years-old child. I believe two families (6 persons) will still be comfortable to stay, which was our plan but our friend family cancelled due to some accident. Ritsuko-san and John gave great and nice helps like friend from when we did reservation, checked in and through checked out in the end.
Some tips I would like to share with next guests
1.	Treat and take care of this house as your own, because the host treat it as for their own living.
2.	The house has 2 floors. If you have child less 3 year old, you need to watch your child carefully and stay at 1st floor as preference.
3.	Tiny and close area for cloths hanging dry.
