Private cabin (9)
I believe the answer is:
stateroom
'private cabin' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stateroom that I've seen before include "Luxury cabin on a liner" , "Place fit for a 27 [PRINCE]" , "Private cabin on board ship" , "Passengers's private compartment on ship" , "luxurious cabin" .)
