We had an amazing time at Pieter's place and highly recommend it. The apartment is in an incredible location directly across from the beach and in close proximity to many sites in Cape Town (including walking distance to the waterfront and many restaurants and parks). We loved the many clever design elements and the efficiency of the space. The apartment is even nicer than the photos let on, with plenty of space for a couple, a great kitchen with tons of countertop space, a washer/dryer, and a nice sitting area with gorgeous views of the beach out the large windows. Pieter was out of town when we were visiting but was very easy to get in touch with as needed via WhatsApp. This is a dream apartment, and we'd gladly stay in it again next time we're lucky enough to visit Cape Town.
One thing to note: It's a fourth floor walk-up, which may pose an issue for some guests, but if that's not a problem for you, you should definitely stay there!
