As others have indicated Sotogrande has some good properties with good gardens and privacy.
We are locating to Alto Sotogrande after living in the South of France for some 30-years and compared to France Sotogrande is very low cost. When we looked around it was interesting that some of the properties had been built and never lived in. The owners had been trying to sell or rent for a while so were prepared to deal on the price - we are renting as getting a resident permit for a US passport holder who has lived in France for 30-years seems beyond the Spanish officials our lawyers have been dealing with.
We viewed several properties that seem to have suffered neglect, some even looked like they had been abandoned.
The area has good golf, horse riding and some excellent eating places.
Can't comment much more as we don't move in 'till 1st Feb, but our search led us to Sotogrande so your may too.
Good luck with your search, there are lots too choose from.
