I visited the Costa del Sol on several occassions and played quite a few courses but never this one being a short par 3 course.
This summer I did visit La Siesta, pretty relaxed ambience! Some friendly local people were playing cards on the veranda of the clubhouse and we had enjoyable round of golf. Although it is a short course there are significant differences in height on some holes which makes it more interesting.
La Siesta is a perfect course to practise your short game.
