Oh you lucky thing! I love Malaga.
The city has everything, shops, culture, architecture and a beach area too. Very like Barcelona would have been before the stag parties I think, and much underrated too.
For three days, I would take a hotel in the city centre as near as possible to Larios Street, the main shopping area and near the Cathedral etc. Do the shopping, Picasso museum, Gibralfaro, and the beach. By the time you have done all that you will need a tapa!
Have a look at this for a few ideas
