I was a little bit let down by the initial cleanliness of this listing. The space simply hadn't been cleaned properly: the floor was covered in dust and hair; the sheets were caked with undissolved detergent; the towels smelled of dirty water. That said, the host provided clean sheets and new towels the next morning.
The location is very convenient to get to or from Haneda airport (appx 50 minutes without transfer on the fantastic Tokyo metro), however, the area itself doesn't have many options in terms of night time dining options or other attractions and it wasn't that conveniently located to areas with such attractions. Also, despite having the windows closed, the ambient noise from the nearby road was quite loud so if you are a light sleeper you may find it an uncomfortable place to sleep.
The shower had good water pressure and it was easy to set my desired water temperature (ie pretty hot).
