K's house was modern, clean and everything you would hope to have in an AirBnB property. It is a big house with plenty of space in common areas (living and dining) and brand new bath/shower.
We stayed as a family of 5 and had more room than we could ask for. Super markets were close by so we had breakfast at home in the morning before we head out to another busy day.
The place perfectly located just 5 min to Sasazuka which is only 1 stop from Shinjuku.
Lastly K and family were so kind and thoughtful, we had nothing to worry about at all.
I'd highly recommend this location to anyone staying in Tokyo, and would look into this property first on my next stay here.
