Presumably spacious accommodation (5)
I believe the answer is:
rooms
'accommodation' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rooms that I've seen before include "Accommodation" , "Indoor spaces" , "Lodges" , "Partitioned parts of a building" , "Quarters" .)
