Hi Rob ,
Balsicas is the nearest village/town. It has its own Rail Station which will connect direct to Madrid and ( I think , Cartagena and Murcia)
Balsicas is only about 5mins drive from SG ; there are a number of shops there , don't know about schools, a Church ( Catholic) and it has grown quite a bit since we first visited the area - this growth will be continue due to all of the developments in the area , and , in a couple of years , there will be the new Int. Airport at Corvera which is only about 15 mins. away by car.
To find out more about Balsicas , have a try at Google Earth or Yahoo
