I'll only give a 70 for my stay in Kyoko houses... Only if the full mark is 10!
Kyoko is a perfect host. She is really helpful throughout my whole trip in Tokyo. She even helped me to rent a WiFi router at the end of my stay in the airbnb and allow me return to her after my whole trip in Japan.
I'll also recommend this house if you're working remotely from Tokyo. The apartment I was in have a working chair and desk, plus a super stable WiFi. The location is really nice. There're a lot of affordable and delicious Japanese restaurants nearby. It's also just a 5 mins train ride from Ikebukuro and around 35mins from Shibuyu. Yet the neighbourhood is really quiet at night.
Give it a try - You won't regret it.
