Apt is very good, clean and new. She has provided kitchen utensils with oil, salt, pepper and tea bags which is very useful for light cooking. It has washing machine, iron, TV with Netflix which was not there in some of the places I stayed. It is close to quick diners, grocery shop. Only inconvenience was you need to goto shinjuki for most of the connecting train lines.
Overall it is an excellent location for staying in Tokyo.
