Help with getting around Saigon (Ho Chi Minh City)

Hi,

I will be moving to Saigon at the end of June and wanted to know a little bit about how to get around the city,
I will be working in the Binh Tan district but would prefer to live more in the centre of town closer to the expat community.
Is it relatively easy to get around?
What are the best means of transport?

Any info would be much appreciated!

All the best,

Florian
