If you don’t want to stay in Atlantis, then I would suggest Parklands, Burgandy Estate or Duynefontein.
Lots of new places they are building in Parklands and Burgandy Estate.
Burgandy Estate has fibre internet, easy to get on N7. Parklands easy to get on N7, not so sure of the fibre.
Duynefontein, think shortest distance to Atlantis, older homes.
