A meanie sent round text on hotel's "poor accommodation" (9)
I believe the answer is:
almshouse
'poor accommodation' is the definition.
(historical type of accommodation for the poor)
'a meanie sent round text on hotel's' is the wordplay.
'meanie' becomes 'louse' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sent round' is an insertion indicator.
'text' becomes 'MS' (short for manuscript).
'on' is a charade indicator (letters next to each other).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'ms'+'h'='msh'
'louse' enclosing 'msh' is 'lmshouse'.
'a'+'lmshouse'='ALMSHOUSE'
Can you help me to learn more?
(Other definitions for almshouse that I've seen before include "Old folks' home (once)" , "home for the poor" , "Shelter charitably provided" , "Endowed lodging for the poor" , "Place for poor" .)
