Definitely recommended for an all-around great experience. The guides and owners are great and you get an intimate feel because of the small size.
Bush camp and Enkewa both are like small oasis in the Mara, and that is saying a lot considering how beautiful the Mara is. Bush camp is surrounded by palm trees and is a short distance to a place in the Sands River where you can cliff jump near a medium-sized waterfall. Drive to some great look-outs over the Serengeti and Sands River.
Great sightings as well. I was there for only two nights and saw EVERYTHING - black rhino, leopard, lion, cheetah, etc. Absolutely beautiful!
