That's the tower at the Parque Comercial, the shopping centre on Mojácar Playa. It's fitted out as a radio station at the moment. The top floor is a small apartment with bathroom. Fine views!

Downstairs, the main part of the set-up (that's on the third floor of the Parque), there are five rooms, a bathroom and a large terrace (on the left of the picture).
Here's the view from the terrace:
