I take along my TomTom and each time use Av. de la Alcanara, 30840, Alhama de Murcia, Spain.
This takes you directly to the perimeter road off the RM23 motorway and does the job.
You can also cut and paste the above into Google maps so as you can see for yourself in advance which always makes sense to me.
What I NEVER use are the obscure addresses albeit each completely different on my water and electricty statements but somehow utility bills always seem to find their way - God knows how!!
Hope this helps.
