Jing's apartment is small but functional,he definitely knew how to use at best every corner of it. If you are a light sleeper maybe you should look somewhere else as you can hear the train at all times (the train station is right next to you). We didn't have any problems as we are used to central London, deaf to any night sounds.
Jing is really quick at responding plus he left us the house spotless.
Definitely recommend it for the prices of Tokyo's rooms.
