Your best bet Andy, is to go to the nearest post office and pay for an Apartado de Correos (P.O. box).  You will have to pay an annual sum for this and they will give you a key for it and it's number.  From then on, your address for post will be  Mr A .........., Apartado de Correos  No. ...,   Gergal (post code), Almería, España.  You will have to check for post every week at least if you are likely to be receiving paper mail.  If you buy anything from Amazon.es or anywhere else online, here may be a pick up place offered, but not if you buy online from a UK site.  This is the best option as otherwise this will be difficult in your area where there are not many foreign residents.
