Shin and Sho's place is definitely a great catch! Cozy, well located and well equipped (we found everything we needed and more). Clean, nice friendly communication, Shin and Sho were very attentive and thoughtful (warning us about the norovirus, checking in every now and then...). The house is only a few minutes from the subway/train rail making it super easy to go around. Vending machines, plenty of restaurants, pharmacies and convenience stores around. The only concern would be if you are a light sleeper as the train track is right next to the house. Although it is a smooth noise, I could see it being a problem for certain people. Shin and Sho have however very nicely included ear plugs if needed (they were not in our case).
Overall, highly recommended if you're looking for a cozy apartment in Tokyo!
P.S. Loved the bathroom!
All the best!
