Having owned a holiday villa in Sotogrande Spain (nr Gibraltar) for 7 years we decided to move here permanantly and have never looked back. Life was great in the UK and Poole Dorset is a wonderful place to live. Having said that the move to Spain for the family has been a dream. For Sports & social in particular the outdoor life makes all the difference.
Sotogrande is special and whilst not as busy as Marbella we love the scenery it offers and the fact that its an urbanization surrounded by beautiful countryside.
If your moving to Spain then consider Sotogrande.
