Character of superior hotel (3)
I believe the answer is:
rho
'character' is the definition.
(rho is a kind of character)
'of superior hotel' is the wordplay.
'of' says the answer is hidden in the clue.
'RHO' is hidden in the letters of 'superior hotel'.
(Other definitions for rho that I've seen before include "Sophocles character" , "Gr. letter written as P" , "letter to Athens" , "Greek character" , "Something like 25 [ETA]" .)
