Marie Jose is a lovely host. She met me out of the taxi even though my flight was late - after 11pm arrival. She kindly provided a number of essentials in the fridge including wine! The apartment was as expected and Marie Jose showed me around and had brochures and leaflets of things going on in Malaga. It is very close to the Historic Centro and there are lots of local bread, fruit, veg shops etc if you plan on cooking at home which I did for the most part.
It is worth checking all the 'Things to know' on the airbnb site if you are a light sleeper. Calle Picacho itself is mostly quiet but as with a lot of Spanish apartments noise can travel through the walls.
