Accommodation

Hi I would like to know the safest and best district to live in easy reach of great hospital and international airport . We are coming in October from NZ thank you

I am moving to HCMC this Sept. I sort of narrowed my choice to D2 at Thao Dien area mainly due to school, and close enough in between airport and my workplace.  There's lots of info on the web to help you decide.

You will find most foreigners in D2 indeed, D1 and D7 as well.
If you want to look for accommodation, don't forget to look into the expat.com housing section or you can check websites like irent.vn

Welcome to Vietnam then (Once you're here)
