Nice-sounding hotel accommodation (5)
I believe the answer is:
suite
'hotel accommodation' is the definition.
(I've seen this in another clue)
'nice-sounding' is the wordplay.
'nice' becomes 'sweet' (both can mean agreeable or pleasant).
'sounding' shows a homophone (sound like).
'sweet' is a homophone of 'SUITE'.
(Other definitions for suite that I've seen before include "Three-piece - -" , "Train; set of rooms" , "Train of followers" , "Adjoining rooms" , "Musical composition" .)
