Claudia is the quintessential peofessional guide.  A good driver, on time, fun to be with, many years of experience and  loves her job.  She can do your bidding or make suggestions and help plan a great day for you with your interests in mind.  Ask her to bring Brian along and you have a walking encyclobedia of the history of Cape Town.  Four of us older travelers spent two full days with Claudia and Brian.  We are very experienced travelers and can be a bit fussy.  No worries here.  If you try booking them and are lucky enough that they are available, you will love them the way we did.
