We've stayed at this apartment for 2 months in March/April of 2020, during Tokyo COVID-19 lockdown.
The apartment was new, it seemed as the building has just opened for short-term rentals with minor decoration works finishing on the 1st floor. It is on a top floor of 6-story building, which is located next to Keikyu Haneda airport line with apartment's main windows and balcony facing south.
The apartment is rather spacious, with a well-equipped kitchen and a nice bathroom. Internet connection is reliable and fast. TV provides about a dozen of standard local channels.
There are trains passing by every 15 minutes, so expect certain noise. Most of the time it's not that loud, but as the building is located exactly opposite the spot where train change rail tracks – sometimes the noise and shaking are rather intrusive. The second bedroom is facing the rail, I guess it can provide rest from 00:30 to 05:00 only, when train traffic suspends.
The neighborhood is ok, with several supermarkets and convenience stores within a walking distance, but it's a basic industrial suburbs (dull) so don't expect anything fancy. A lot of families with kids, senior citizens, no parks (or any foliage for that matter). However, it provides a good connection to Haneda, Kawasaki, Yokohama and Tokyo is not that far away either.
During our stay we've requested an extension twice, both receiving a quotation from host via Airbnb with original reservation price doubled. This was fixed by the host, claiming the mistake, although it was a surprise receiving an inflated bill the second time.
