Namely, awfully nice and picturesque (6)
I believe the answer is:
scenic
'picturesque' is the definition.
(thesaurus)
'namely awfully nice' is the wordplay.
'namely' becomes 'sc' (I've seen this in other clues).
'awfully' indicates an anagram.
'nice' with letters rearranged gives 'enic'.
'sc'+'enic'='SCENIC'
'and' is the link.
(Other definitions for scenic that I've seen before include "This route has nice scenery" , "Such a railway" , "Like an impressive view" , "having a striking view" , "Of route, having pleasent views" .)
