As with every place in South Africa we were a bit concerned about the safety, and as with every place we have been concerned about we were obviously wrong about Cape Town as well. We were never out during night time so things obviously change by then. Knowing this we took an Uber everywhere, day or evening, and we had no problem being picked up right outside the gates.
Scotts apartment is securely located at one of the more well regraded streets in Cape Town, behind several locked doors with a security guard. The area is a bit busy, but it didn't bother us at all. Lots of good coffee places, restaurants and convenience stores nearby and it's in close proximity to the waterfront and other attractions like tour guides etc.
The view from the apartment is absolutely breathtaking and it's amazing to see the clouds engulfing the mountain range on cloudy days if you're not used these sort of things.
Scott and Angie were very communicative and were quick to respond to any issues and questions we had. Great hosts. If you're going to Cape Town to experience what the city has to offer, I can really recommend staying at Scotts place.
