Regarding areas etc. I have just been looking on Agents websites like fotocasa.es etc, for sales and rentals in La Cala de Mijas and was amazed at how many were on offer.
Having lived there before I know the area well, I have noticed a lot of the properties are not even in La Cala itself.
So for people not in the know, anything that mentions Rivera del sol, Calahonda, Mijas Costa etc, are not actually in La Cala but close by. Torrenueva joins La Cala and is also nice.
I can only guess that the agents know that it is a desireable place to live and so advertise the other properties as actually being there. Karen
