The apartment is nicely located. From the house you can hike Table Mountain on the "Pipe Trail" - fantastic and much better than the cable car!!
But you need a car if you want to discover Camps Bay, Cape Town and the Western Cape (however Cape Town has a relatively good public transport system).
If you love the sun, you need to wait till noon (at least in April) to get in the veranda but you will see the sunset over the Ocean.
