Brought by some guru to piazza, a perfect spot! (6)
I believe the answer is:
utopia
'a perfect spot' is the definition.
(I've seen this in another clue)
'brought by some guru to piazza' is the wordplay.
'brought by some' indicates the answer is hidden within the clue.
'UTOPIA' is hidden within 'guru to piazza'.
(Other definitions for utopia that I've seen before include "Thomas More's perfect society" , "Sir Thomas More's ideal society" , "Thomas More's ideal state" , "Imaginary ideal place" , "More's imaginary state" .)
