Hi I have added the Don Carlos to our reviews site, so hopefully somebody will submit a review here

Don Carlos is a good few kilometers from the centre of Marbella, it is near the Elviria exit on the A7/N340. You will definitely need a car. Sorry never stayed there, just had a drink there one evening, seems very nice and is the only tall building right on that part of the coast.

Its right on probably the best beach in marbella, you would need a car though to get the best out of the holiday. Its about 5 mins drive from marbella centre. Great beach club in summer (Nikki Beach..expensive!)
