I spent a wonderful stay at Anna and Giovanni's.
The appartment was super clean, there were towels and all you need to make a small breakfast each day. A cleaning lady also came during my stay (10 days) to make sure everything will stay clean.
Anna and Giovanni were also very helpful. They brought me kitchen tools when I asked some and kindly came to open the door within 5 minutes when I locked myself out.
The courtyard is besides super nice with bushes of colourful flowers.
I recommend this apartment in Nardo, that is also very well located - 1 min walk from the main square.
