Most of the buildings on the farm date back more than 100 years and were built with clay bricks. These buildings have been renovated to their former glory. The first unit was renovated in 2004. De Denne Country Guesthouse is not affected by loadshedding, as all units are connected to inverters.

Johan and Louise Keller, owners of De Denne Country Guest House, are the 4th generation of the Keller family to farm on the De Denne Farm. They have 4 children Helene-Marie, Pieter, Jeru and Aike.

The towns of Oudtshoorn and De Rust are in the Klein Karoo between the Swartberg and Outeniqua mountains. Oudtshoorn is the ostrich capital of the world. The world's biggest bird is just one of the many attractions in this area of exceptional contrasts and natural beauty. The region is home to the spectacular Cango Caves, Africa's largest show cave system; an ecological hotspot where three distinct plant biomes (succulent karoo, cape thicket and fynbos) converge; and the Swartberg mountain range, which is part of the Cape Floral World Heritage Site.
