A slap-up spread somewhere in Scandinavia (7)

I believe the answer is:

uppsala

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

'somewhere in scandinavia' is the definition.
The definition suggests a singular noun which matches the answer.

'a slap-up spread' is the wordplay.
'spread' indicates anagramming the letters.
'a'+'slap'+'up'='aslapup'
'aslapup' with letters rearranged gives 'UPPSALA'.

Can you help me to learn more?

(Other definitions for uppsala that I've seen before include "Town with oldest Swedish university" , "Would the Swedish city appal us?" , "City NW of Stockholm" , "City in Sweden" .)

I've seen this clue in The Independent.
