Ah, so you know the area well! The infrastructure in Andalucia was pretty "thin" towards the end of the Franco era (I was there 1972-80). I returned many years later; my parents lived as retired expats in La Linea and San Roque till my stepdad passed away in 2010... and things had certainly changed extensively.

I do enjoy the silence and the "sound" of all the electrical hums being OFF.
