Hopes dashed with foul, inferior accommodation (9)

I believe the answer is:

flophouse

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

'inferior accommodation' is the definition.
'flophouse' can be an answer for 'accommodation' (flophouse is a kind of accommodation). I'm not certain of the 'inferior' bit.

'hopes dashed with foul' is the wordplay.
'dashed with' indicates anagramming the letters.
'hopes' with its letters anagrammed with 'foul' makes 'FLOPHOUSE'.

Can you help me to learn more?

(Another definition for flophouse that I've seen is " Low-budget version of Hotel".)

I've seen this clue in The Guardian.
