About the area:
Johannesburg is where the money is. And the action. It's the most powerful commercial centre on the African continent. It is an African city that works: the phones dial, the lights switch on, you can drink the water, there are multi-lane freeways, skyscrapers, conference centres, golf courses. If you should get lost, ordinary people on the street speak English. Cellphones are everywhere. You can send e-mail from your hotel room, you can bank any foreign currency, and you can watch CNN.
Johannesburg hosts every form of commercial activity from financial services to heavy industries and mining. There's hardly a major international company doing serious business in sub-Saharan Africa that has not looked to Johannesburg as the gateway to the continent.
