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.
