I stayed at Kazumi's apartment for my last two weeks in Japan, after having lived in Kanagawa for one year. I have stayed at multiple airbnbs in Japan already (albeit outside of Tokyo), but Kazumi's apartment is definitely one of the nicer ones. Everything was very clean and cozy and it was equipped with household items I missed in other airbnbs (for example a sufficient amount of hangers, clothespins and a vacuum cleaner).
The location is quite convenient, with a supermarket, drugstore, 100 Yen shop and the station less than five minutes away from the apartment. There are also some restaurants in Kita-Akabane and a lot more in Akabane. Moreover, you can get super fast to Ikebukuro and Shinjuku - places I hardly ever visited while living in Kanagawa, because they were just too far away. I probably went to Ikebukuro around four times during my stay at Kazumi's apartment.
Kazumi herself is also very hospitable and helpful. I contacted her a couple of times and she always replied back quickly. I met up with her and her super cute daughter once; she showed me the area around Akabane station and we had dinner together. She was really friendly and I had a lot of fun that evening. :)
I can definitely recommend staying at Kazumi's apartment!
