Nice 2 floor house very close to Shin Okhubo station. Steve was very nice, unlike any other host we've ever had he met us at the station, accomodated us early due to a change in travel plans, and walked us to the site and gave us a detailed tour.
The walk to the *east* exit of Shinjuku station is about 10-12 mins and the south exit about 20. You can get to Shin Okubu in under 5 mins so if you have a JR rail pass it's easily accessible.
You are also very close to Kabukicho about 10 mins.
We had the upstairs room, it was very clean and spacious. Steve provided access to laundry and a shared kitchen and private shower and toilet. We could also use his Apple TV which was great.
The only concerns which we had and are minor are that in the evening and morning you will hear the trains so if you're a light sleeper heads up. We were also lucky to have quiet neighbors downstairs. We also found the price to be a bit high considering you could get a hotel room for another $20-30.
Overall great stay, thank you!
