Does anybody know some good and safe hotels or guesthouses in Capetown?

I am going to Capetown 27th Feb. Any ideas about where I should stay? I am then flying home to Australia.Yay. I will be in Capetown about 10 days and the reason is to have jaw surgery which I have badly needed. I am going to Australia on March 13. Any help will be much appreciated (for example) bedsits, best place, etc. I have been reading all this Pistorius stuff and now I’m scared! (The crime rate). I will be by myself. I have been to Durban and it didn’t seem scary. Thanks!
