I stayed here a few years ago, they have a shuttle to the MRT near city hall and there is also a bus service which takes about 20 min. The lounge food was not that great and limited selection. Not a good location for visiting the city. Since then I have stayed at FX Hotel on Nanjing East and City Inn Suites III near the main station, both better locations but no breakfast facilities. June will be very hot, you will not want an extra commute with kids.
