Just a quick note to say tourists should have no problems in Cape Town right now.
We have arrived a few days ago. We are staying at a hotel. The only difference we noticed is no bath, water flow at the hand wash faucet at public toilets turned down. That is about it. Cleanliness etc is still of a hight standard, plenty of mineral water available.
Having a great time, would not hesitate to recommend the city to anyone.
