Fellow outside hotel in Belgian city (5)
I believe the answer is:
ghent
'belgian city' is the definition.
(I've seen this in another clue)
'fellow outside hotel' is the wordplay.
'fellow' becomes 'gent' (synonyms).
'outside' indicates putting letters inside (some letters go outside others).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'gent' placed around 'h' is 'GHENT'.
'in' is the link.
(Other definitions for ghent that I've seen before include "source of good news" , "European city" , "Flanders city/port" , "NW Belgian city" , "City of northwest Belgium, known for its cloth industry" .)
