The hosts are great! Mr. Hisao is a stern-looking quiet man but very considerate. His wife is also very kind and offered to help me carry my things to the station before Mr. Hisao took me to the station in his car (which was a big help with all my luggage). The small breakfasts were also a very tasty wonderful surprise that I looked forward to each morning.
It was a little difficult to use the microwave and A/C without English instructions but the bathroom was very intuitive (for westerners). Towels, hair dryer, hangers were provided. There was a washer on the ground floor that cost 200 yen (packages of detergent were in the room).
It was easy to access and about a 10 minute walk to Uguisudani station (north entrance). Just note that the elevators at Uguisudani are at the south entrance and a long walk with baggage. The airbnb is about a 15-20 minute walk to Nippori station (with easy elevator access). Nippori and Uguisudani were both on the Yamanote Line so it had easy access to the rest of Tokyo.
