Malaga city, stay one night there. Lovely city esp on the weekends. Buzzing, and great shopping and the best tapas too. Fabulous beach area, reminds me of Barcelona without the stags and hens.
Then on to Estepona. Cannot be beaten for a fabulous beach, and a Spanish working town with great atmosphere, bars, and restaurants. No lager louts either, too far down the coast for that. I really like it.
Then drive to Cadiz. Wonderful spot, you will like it I know you will. Then up to Seville for a few days. Another magic city. Spain is full of them, each wonderful. Then over the mountains from Seville to Ronda. The views are amazing, and the drive is white knuckle, not for the faint hearted.
And back to Malaga.
We have done this route, and it is fantastic. We had 15 days though, so you may tailor it a bit, if it sounds too much.
Enjoy. I just love Andalucia.
