Hi, we have lived here for 20 years and lived in Benijofar. Three years ago we moved to live in El Chaparral which is near San Luis/La Siesta. The reason we moved was to be near busses, bars, shops etc., and also to not be far from Torrevieja beaches. As you get a little older you will find the busses are necessary so I suggest you have a look at El Chaparral, San Luis and La Siesta, you may enjoy those areas.
Also you will need to think of your hobbies and what you want to do in your spare time. Where you live will make it easier or harder to get to the things you want to do, hence El Chaparral is easy to get to all areas due to the bus service.
Good luck,
