I highly recommend this operator. We received excellent communication from Robert in advance of the safari and he even followed-up afterwards to make sure everything went according to plan. Unexpectedly, we ended up being the only 2 people in the group, so we received our own private guide and 4x4 at no extra charge. The camps and lodges we stayed at were fantastic - the one in Amboseli was a luxury stay, with an excellent pool and spa. Simon was an excellent guide and we saw everything we wanted to see and more.
Overall, much more than I expected from a more budget operator like this - in fact, probably comparable to most higher-end private safaris.
