Reported: on the immediately prior question, Duo defined une terasse as a deck; then marked it wrong here.
8 months later they still haven't fixed it. Deck was rejected 3 Feb 2021.
balcony is the usual word
Would suggest the word balcony is what is commonly used.
I don't think it is clear whether that is what is meant here. A balcony would usually be "un balcon", I believe. This might even be a roof terrace or, as our American cousins think, a deck.
or a patio
Alternative answer :-
"We rented an apartment with a patio"
