House that is free around the centre of Marrakech (4)

I believe the answer is:

riad

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

'house that' is the definition.
I know nothing about this answer so I can't tell whether this works.

'free around the centre of marrakech' is the wordplay.
'free' becomes 'rid' (to be free of something is to be rid of it).
'around' means one lot of letters goes inside another.
'the centre of' says to take the centre.
The middle letter of 'marrakech' is 'a'.
'rid' placed around 'a' is 'RIAD'.

'is' acts as a link.

Can you help me to learn more?
