Delight recalling well-kept hotel (5)
I believe the answer is:
mirth
'delight' is the definition.
(thesaurus)
'recalling well-kept hotel' is the wordplay.
'recalling' says the letters should be written in reverse.
'well-kept' becomes 'trim' ('trim' can be a synonym of 'well-kept').
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'trim' reversed gives 'mirt'.
'mirt'+'h'='MIRTH'
(Other definitions for mirth that I've seen before include "Glee" , "Amusement - jollity" , "funny feeling" , "Laughter" , "Jocularity" .)
