Fancy hotel for a serf (5)
I believe the answer is:
helot
'a serf' is the definition.
('helot' can be a synonym of 'serf')
'fancy hotel' is the wordplay.
'fancy' is an anagram indicator.
'hotel' is an anagram of 'HELOT'.
'for' acts as a link.
(Other definitions for helot that I've seen before include "downtrodden?" , "Greek serf" , "One made to work" , "Spartan serf" , "Serf of ancient Sparta" .)
