Yuki was great and her place was perfect. The pictures honestly don't do it justice. It is beautiful. I stayed in four different Airbnb's during my trip (all in the same price range), and Yuki's felt like a luxury hotel / oasis in a sea of decent, ordinary places. She keeps the flat pristinely clean, and with wood floors, floor-to-ceiling windows in the bedroom that let a ton of light in, and an extremely comfortable, big bed, I could not have dreamed of a more perfect home base for Tokyo. The neighborhood is quiet and gorgeous with narrow winding streets, and it really is a 3 minute walk to the station, which is extra wonderful if you have a JR pass. Also, this flat was 3x bigger than any of the other places I stayed.
Net net: clean, comfortable, beautiful, great neighborhood (a bit far from center of Tokyo but everything was so so easy to get to that this hardly even feels worth mentioning), safe, and Yuki was a WONDERFUL host. She was very responsive, helped me with a ton of things, and gave great tips. I could go on and on because that's how much I loved it but I'll stop there. If possible, I'll book my entire trip here next time.
