This is a good place to stay if you are interested in nightlife. Otherwise, as mentioned by other reviews, you may find it difficult to sleep due to the presence of two bars on the street below the apartment. The windows of the apartment face the street and the party can go on for a while. We also found the bed to be too high lofted, with a ladder system that was not easy to get up and down (though we are young and fit). We slept below on the couch. We only stayed two nights, any more would have been uncomfortable.
That being said, it is in a favorable location to explore the old town in Málaga - bars, restaurants, and museums - and it is easy to get to the beach on foot too.
