if you have a chance, visit the MEzquita on a Sunday afternoon, at about 3 or 4 pm, when everybody is having lunch and the place is virtually deserted.
PURE MAGIC (and I am from Granada myself).
If in Granada, try likewise to visit the Alhambra on the week inmediately after Easter, and at 3 pm or so, if you are lucky (it only happened to me once), you might be nearly alone, and then you discover a whole new place, silence, the fountains, it is something completely different!
Buen viaje!
