A place of respectable tone (4)

I believe the answer is:

eton

'a place' is the definition.
(Eton matches up with the definition a place)

'of respectable tone' is the wordplay.
'of' indicates the answer is hidden within the clue.
'ETON' is hidden in the letters of 'respectable tone'.

(Other definitions for eton that I've seen before include "Easy to understand" , "Public school founded by Henry VI" , "Independent school" , "English college of note" , "Posh college" .)

I've seen this clue in the Evening Standard.
