Accommodation of interest to key players (5)
I believe the answer is:
flats
'key players' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'accommodation of interest' is the wordplay.
'accommodation' becomes 'flat' (I've seen this before).
'of interest' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'flat'+'s'='FLATS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for flats that I've seen before include "Punctures" , "Apartments" , "As opposed to sharps?" .)
