'couple can't be accommodated here' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'only one space' is the wordplay.
'only one' becomes 'single' (I've seen this before).
'space' becomes 'room' (enough space or room to do something).
'single'+'room'='SINGLE ROOM'

'so' acts as a link.
