Koos's place is located very close to some amazing cafés and restaurants in Sea Point. We really liked the neighborhood! I also loved that the airbnb had almost everything you might need: A washing machine, a smoothie maker, a big fridge, good wifi, a toaster, etc.
Overall, the apartment wasn't brand new or renovated. The sofa had quite a few stains and some kitchen drawers might need to be cleaned out at some point. It didn't bother us too much, since we only spent a couple of days there.
There are two doors at the main entrance and two doors (one regular door and one gate) at the apartment, which made it feel quite safe. They also gave us pepper spray upon arrival.
The host (or rather his team) were responsive and friendly!
