I am Spanish and I am at a time in my life when I want to visit all the charming villages in Spain.

That's really cool. Three villages from the south that come to mind are Frigiliana. Setenil De Las Bodegas and Benahavís. I did a post about Setenil De Las Bodegas s few days ago as I was there in February, beautiful village.

The influence of the south is very noticeable by its white houses with blue decorations.

Yes. I love this and the mountains appeal to me too.
