I have recently started thinking about Airbnb after having heard a bit about it on a BP podcast. It's something I might pursue in the future, but living abroad currently makes something that's management intensive like Airbnb a bit of a challenge.
In terms of SA, Cape Town (and the Western Cape) is an excellent place to invest compared to the rest of the country. Although at the moment the prices are quite high, that being said the province is receiving a huge influx of people and so demand keeps rising.
I am not too familiar with laws in terms of foreign investors but I recall reading that it is pretty favorable. But It's best to look into this yourself to be safe.
Because of the high prices currently, price/rent ratio and be tricky but it is still manageable in many areas and it's not hard too find good deals from time to time. Something like Airbnb definitely has the income potential to justify prices if done correctly I think.
I suggest you look at property24.com and private property.co.za as these are the sites I use to keep tabs on the market.
If you have any further questions about the SA market feel free to reach out to at any point :)
