Pretty good advice there from aussiefarmer.
Just to add that the age of the villas in South can range from being quite new to a few years old and the buildings and the interiors age fast, mainly due to the standard of construction. 'A' villas are the oldest and 'H' villas are still very new. Villas in Heights are smaller and are designed in a terraced layout, whereas villas in South are semi-detached and don't feel quite so hemmed in. Gardens in Heights are barely big enough to swing a cat but there is a lot more space in South. Personally, I think Heights has better facilities on site than South does but then again, things are not that far away by car anyway. It's all very subjective at the end of the day.
I stay in South and I don't dislike it, nor am I in love it but it suits me. More importantly, I don't feel at work when I am not at work but that very much depends on who your neighbours are and mine are friendly yet reserved, which suits me perfectly. Nothing worse than getting embroiled into a conversation about work as soon as you step out the house and see your neighbour!
