Unfortunately I never had one of the awesome rooms - the ones that face Table Mountain and the setting sun! So, if you plan on staying at the Westin, try to organise that you get a room facing Signal Hill's direction. :)
Below are a few more photos taken from my room on the 8th floor - a little later in the evening.
