This location is good, being close to Kamata station and there were many eating places around and near to Haneda airport, cost me about 3,000 yen for a taxi to Haneda airport. However this location is not very suitable to stay with your family and kids as there are many touts and pimps around at night pestering you - "massage" and sex.
They are very particular about checkout timing i.e. 10am and anything later, you are required to pay extra changes. So travelers, do take note.
