Stablehands dismissing initial accommodation (5)

I believe the answer is:

rooms

I'm a little stuck... Click here to teach me more about this clue!

'accommodation' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for rooms that I've seen before include "Living spaces in buildings (5)" , "Apartments" , "Partitioned parts of a building" , "Quarters" , "Lodges" .)

I've seen this clue in The Independent.
