Shohei is a great host, and responded quite quickly to our queries. He lives in the same complex as the property he's renting out so reaching him is quite easy.
His place is a bit of a walk from either Sasazuka or Daitabashi station, but nothing too daunting. At any rate, there's a bus stop bound for Shibuya Station just a few meters walk from his place, so transportation wise, it's very convenient.
The space is small, but maximized for efficiency, with complete amenities-- washing machine, TV, microwave, hairdryer. He educates you on how the garbage is segregated first thing, which is very helpful when sorting out the trash you accumulate during your stay.
Overall, I highly recommend his place for small groups (2-3) or solo travelers, especially those who want good value for money!
