Teaching in Jakarta

Hi there

I'm thinking about apply for a job as a teacher, teaching English as a second language. Does anyone have any tips for me about accommodation, acceptable pay, cost of living etc. I'm looking to apply to the Wall Street Institute. Has anyone had dealings with them or heard about them? Als o I have type one diabetes. Does anyone know about the health care in Jacarta, for example would I be able to buy insuline cheap enough or would I be better off getting a years supply from my own doctor (if possible)?

Thanks
Alison
