Roomy and deceptively attractive with area for a bit of exercise (8)
I believe the answer is:
spacious
'roomy' is the definition.
(synonyms)
'deceptively attractive with area for a bit of exercise' is the wordplay.
I cannot really understand how this works, but
'area' could be 'spa' (spa is a kind of area) and 'spa' is found in the answer.
'of' could be 'o' and 'o' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for spacious that I've seen before include "Having plenty of room" , "Roomy or expansive" , "Big and roomy" , "Ample, roomy" , "Roomy, not congested" .)
