We had a great 7-night stay at Peter and Judi's place. Beautiful and clean apartment, high quality furnishings, great view from the living room, even fresh fruit on arrival. Very handy to be part of a small shopping mall, especially for meals and groceries. We drove to Simonstown every day at sunset, to walk past the penguins - it is only a 5-10 minute drive. Initially we were a bit worried about traffic noise, but it was mostly not a problem, as the noise was a good blend of crashing waves, wind and light traffic noise, nothing obnoxious.
Bring a sleeping mask if light bothers you - the curtains are not blackout. The other thing that caused some anxiety at times: To enter the building, you receive a link to click, this then generates a QR code to scan at the door. But our phone data signal was particularly poor at times (Vodacom). If that happens to you, you need to walk around the mall until you find a spot with good reception to click the link! Take a daily screenshot of the QR.
