We stayed 2 nights. The TV was turning on automatically twice in the very early morning around 4:30 AM and 5:00 AM at second night, and cleaning staff didn’t check the alarm clock was still remained ON (previous guest’s setting) causing the unnecessary disturbance of sleeping due unexpected went off at 6:30 AM on the second day morning.
It's near the JR Kamata Station and the Keikyu Kamata Station. This is not a big station but there are quite a number of restaurants nearby, and department stores in both stations. It is near to the Haneda Airport. However, I came from Narita Airport. Though it is far away but still quite convenient.
EXCELLENT LOCATION, but not too clean and has smoking smell coming from other floors in the hall way. But very close to the airport and train/ JR station.
