Likable or gratifying (8)
I believe the answer is:
pleasing
This clue is a double definition.
'likable' is the first definition.
(thesaurus)
'gratifying' is the second definition.
(pleasing is a kind of gratifying)
(Other definitions for pleasing that I've seen before include "making one happy" , "Satisfying or appealing" , "agreeable - with 13d" , "Delightful" , "Pleasurable; satisfying" .)
