Rumika was a great communicator. We were staying during Typhoon Hagibis and Rumika stayed in constant communication providing updates. The place is exceptionally large for Tokyo and very conveniently located to many restaurants and grocery stores.
Please note that the closest subway station to the Airbnb is Hatsudai and it is on the New Keio Line. For those with the JR pass, the pass cannot be used for the New Keio Line; you must transfer at Shinjuku station, which is one stop away.
