Miss uneven Buena Vista apartment (4)
I believe the answer is:
unit
'apartment' is the definition.
(I know that apartment can be written as unit)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for unit that I've seen before include "A considerable number of soldiers" , "Subdivision of a whole" , "One - kitchen cabinet" , "Single item, maybe part of a set" , "Individual thing or group regarded as complete" .)
