That's certainly the Bloubergstrand area. Best option is to have a Google session. Price will depend greatly on when you choose to go. If you're planning on staying for a few months, you'll probably get a better rate. We used to live in Atlantic Beach Golf Estate a cpl km down the road in Melkbosstrand. Lovely estate, though possibly a bit pricey. Eden on the Bay and Seaside Village are two other nice complexes up in Big Bay. You've then got countless apartments along Otto du Plessis Drive etc. Horizon, Dolphin Ridge, Waves Edge, Infinity etc etc etc........
Two of the larger real estate companies are Seef and Remax.

Also worth looking on Gumtree. Look for properties for rent around Bloubergstrand, Table View, Big Bay, Eden on Bay, Seaside Village, Melkbosstrand etc. http://capetown-westerncape.gumtree.co.za/f-Real-Estate-houses-flats-for-rent-West-Coast-W0QQCatIdZ9071QQLocationZ3100010

I'd strongly recommend tagging your board with a cell phone number too. Soooo many boards get lost and turn up. With a huge kiting scene, chances are your board will get picked up by a fellow kiter and dropped in one of the many shops. It's far easier if theres a number on it! Swell can be big, and currents can be strong. I've lost two boards. One was picked up 11 miles offsore by a yachtsman! Langebaan can swallow boards if the tide is running.
It's getting more n more expensive to live in Cape Town now. Cost of living has soared in last few years, so you don't get as much for your $$$ as you might once have done so, but it's still without doubt my favourite place in the world.
