Contrary to what’s been written, Torrevieja (and Villamartin) suits some people because of the facilities, English widely spoken and the high proportion of expats living there. Gives a certain amount of security to some. Others seek a quieter, remote and more Spanish lifestyle, depends on what you like.
That’s certainly correct, it does suit many people. However, I do wonder how viable it is to live long term in an English ghetto. The facilites for Brits are good though, and the new hospital is very good IME, no need to speak Spanish to get good healthcare.
From an investment perspective though, I do think Torre is a poor choice.
