I’m not an estate agent and I’ve lived longer on the CDS than the Costa Blanca. But getting personal is counter productive.
Your main point concerned an assertion that Spanish people prefer Brits to other Europeans. That simply isn’t true. History can teach us all, especially history from not that long ago.
There is an historical alignment between Spain, Germany and Italy, and historical disagreement between the Spanish and the British empires even longer ago.
It’s not a big deal all these years later, but to suggest that Spanish people prefer Brits to other Europeans is daft and needed commenting on.
