We are a family of 5 and stayed for 7 nights. The beds are comfortable and the sofa bed is not bad too. We have quite a lot of luggages, but it is spacious enough to fit them in.
It is convenient for travelers who need to access to Haneda Airport. There are also many restaurants and convenience stores around.
The sound from outside like cars passing by is quite apparent. On top of that, ambulances pass by quite frequently. If you are sensitive to sound, maybe it is not an ideal place.
There is instruction for looking for the place for those who come from Keikyu Kamata Station, but not from Kamata Station. So I used map application to look for the place and it had taken me awhile, as the apartment is not apparent among the hotels and inns nearby.
The place is clean and neat, except the window to the balcony and the balcony itself. But it is not a big deal if you keep the curtains drawn.
In overall it is a stay that worths the price. Thank you for letting us staying there.
