I'm in/at my apartment in Chicago.
Both ok? If yes, would you then prefer 'at' so 'in' is not used twice in the sentence?
I find "at" slightly preferable in this sentence, probably because it is more location-focused, which seems to suit "in Chicago". It does also avoid the repetition of "in", though I don't find this repetition in itself too bothersome. Generally speaking (ignoring the "location-focused" issue of this sentence), if you are inside the apartment then both "at" and "in" may be used; however, if you are just outside then "at" can be used but not "in".
