Decent hotel on East Street (6)
I believe the answer is:
honest
'decent' is the definition.
(thesaurus)
'hotel on east street' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'east' becomes 'e' ('E' can be a synonym of 'east').
'street' becomes 'st'.
'h'+'on'+'e'+'st'='HONEST'
(Other definitions for honest that I've seen before include "Truthful in manner" , "Sincere, truthful" , "Reliable - the son (anag)" , "Upright and straightforward" , "Truthful and dependable" .)
