In the same place I stay overlooking Malta’s capital (6)
I believe the answer is:
ibidem
'in the same place' is the definition.
(synonyms)
'i stay overlooking malta's capital' is the wordplay.
'stay' becomes 'bide' (biding is a kind of staying).
'overlooking' is a charade indicator (letters next to each other) (in a down clue, some letters go above others).
'capital' says to take the initial letters.
The initial letter of 'malta' is 'm'.
'i'+'bide'+'m'='IBIDEM'
(Other definitions for ibidem that I've seen before include "In the same place as previously mentioned" , "In the same place (Latin)" , "In the same place, used in referencing" , "Previously cited (in this book)" , "In the same source (Latin)" .)
