Shin and Sho have a lovely home and made our experience in Japan amazing. The hosts provided very easy instructions for the house as far as check-in/out and using the electronics of the home. The house is roughly a 10 minute walk from the Higashi-Nakano and Oedo Subway train stations through a quiet neighborhood and is near many food shops/convenience stores. From these stations you can get pretty much anywhere you need to (less than 5 minute ride to/from Shinjuku Station).
The hosts were very responsive to messages and checked on us often which was very helpful. The house is quaint but very clean, with great amenities, Mobile WiFi, heated toilets w/bidets, large flat screen television, large shower, washer/dryer unit, as well as air conditioning. There is a train track very near to the house that multiple trains run through until about midnight, and start back up at about 4am, the noise is not very loud but still noticeable so if you are a light sleeper please be aware. This is a great home for your stay in Japan and we would definitely stay here in the future.
