Concierge's workplace (5)
I believe the answer is:
hotel
'concierge's workplace' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hotel that I've seen before include "Building with rooms to stay in" , "Code word for letter H" , "Eg, Savoy, Ritz" , "It keeps guests" , "A modern inn" .)
