I returned from Cape Town a few days ago with a friend of mine, and made some awesome experiences, at first: the kite lessons were excellent! After i came as a complete kitesurfing novice to cape town, i can truly say that after a good piece of work, i am on the best way to become a good kitesurfer.
I also enjoyed the good weather, and the friendly atmosphere at the house. Everything was really peaceful and relaxed.
If you want to travel to Cape Town, try the meat! It is really really really good! We made a barbecue at the house, which i definitely will miss sadly.
My conclusion is that kitekahunas is a nice place to stay and to improve your kitesurfing skills - even if your a beginner, they know to handle it.
