I went there with my family last year. It was absolutely fantastic. We got in touch with Jock Anderson, a safari guide with over 40 years experience who just knew everything there was to know about Kenya and the wildlife.
The company is private, and although fairly expensive, it is the perfect way to experience the bush as it's a camp set up purely for you, wherever you want it. It is extemely luxurious and the food is fantastic. The staff are welcoming and helpful. In my opinion there is no better way of seeing Kenya if you do not like millions of tourists.
