Unfriendly; unpleasant (12)

I believe the answer is:

disagreeable

I believe this clue is a double definition.

'unfriendly' is the first definition.
(thesaurus)

'unpleasant' is the second definition.
(similar in meaning)

(Other definitions for disagreeable that I've seen before include "Bad-tempered" , "Obnoxious" , "Unpleasant" , "Offensive - peevish" .)

I've seen this clue in The Times.
