My family and I stayed at Key West during my graduation week. It was a wonderful apartment with extremely comfortable beds and an amazing view of Table Mountain and the ocean. I would definitely recommend it to anyone with a full family travelling to the Cape. Everything is approximately 20 minutes away (Canal Walk, V&A Waterfront, Airport). The fridge is big if you like to store things and the kitchen is well equipped for self-catering.
Will definitely come again.
