Everything was perfect! You find the flat "in the heart" of the city, everything you need is around you (the center, bars, restauraunts, night life ;)). There is only a 15 minute walk to the beach and you need 3-5 minutes to the center of Málaga.
The communication with Marián and Manolo was great...they had "lo más importante" prepared in the fridge: cerveza y agua.
I totally recommend the aparment and the city. It was a wonderful (short) vacation :)
