Really depends on what you like to do. We are older, and enjoy the true history, and flavor of Spain which, (IMO) can only be experienced in the south, Andalucia, Costa Del Sol.

We take Air France out of Dulles to Paris, and then a quick flight down to
Malaga. A short taxi ride to Hertz car rental in Marbella, and drive to our time-share in Elviria which has a large population of Brits. Even has a local radio station.

Granada, Seville, Ronda, Gibraltar, Mijas, etc are all a day trip from there.
The resort has a restaurant, and bar with live music. Across the street is an English pub, and grocery store. Down on the beach, (a short walk) is another bar, and restaurant.
Could probably make you a deal with renting, wife and I have 8 weeks a
year, and with enough notice can book almost anywhere in the world.
