A good place for Adam's ale (3)

I believe the answer is:

spa

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

'a good place' is the definition.
'spa' can be an answer for 'place' (I have seen 'place of treatment' mean 'spa' so perhaps 'place' could also mean 'spa'). I'm not certain of the 'a good' bit.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for spa that I've seen before include "hydro" , "Healthy place" , "eg Bath" , "A therapeutic hot spring" , "Water-cure town" .)

I've seen this clue in the Evening Standard.
