I flat out loved Desert Camp. When going to Sossusvlei, location was a big consideration in choosing lodging for me and my wife. We wanted to be as close as possible, to catch early morning photos at Sossus & Deadvlei, but didn't want to camp or dole out $$$ for the lodge inside the park gates. Sossusvlei Lodge (the sister property for Desert Camp) was also expensive and luxurious, but too expensive for us.
At Desert Camp, we got privacy in our own cabin and were very comfortable. It felt like very posh camping -- the rooms were clean, spacious, comfortable, yet maintained a camping vibe. There was unlimited wifi, and the connection was good. The grounds were beautiful, and we had oryx grazing in our backyard. For meals, we brought most of our own food and ate at the Sossusvlei Lodge for a dinner buffet one night (Desert Camp made reservations for us).
Overall, it seemed to be a cost-efficient and comfortable place to stay. It felt like self-catering lodge, but with access to a fancier hotel/lodge just down the street for meals if needed. Braai options are available, which we did not utilise. We would recommend Desert Camp as a good option for our friends who visit Sossusvlei.
