We stayed in the chalet accommodation. Thanks to the consideration of the kind and friendly owner, we had two adjoining units. The units were reasonably well equipped for a self catering stay. Everything was clean, apart from the braai grid, for which I had to spend an hour of scrubbing in order to make it usable.
We were warm enough, despite the winter chill, thanks to the cosy bedding. There was air conditioning in the two units, but only one had a "warm" option.
Take note that one can hear EVERYTHING going on in the adjoining unit, whether it is conversation, snoring or whatever.
The campsite was peaceful, with some springbok roaming freely. The night sky was very clear, and only slightly impacted by the lights of Upington at 13km from the site. However, despite the address of the site, it is important to highlight that there is no affiliation with the nature reserve across the road, so no opportunity for one to visit there for game viewing.
In summary, this is a clean and peaceful site well suited to travellers on their way to or back from Namibia or the Kalahari. We used it as a base to explore the Green Kalahari area for a day or so. It is only a campsite though, not a reserve, and try to avoid having noisy neighbours.
