I bet it's lovely, Gaa. We need to know where you live to answer your question . . . if you are in the UK the Olive will need protection in the cold months. Any frost-free place should be fine, with good light, and occasional watering.

Yea, depends where you are and how bad the winter is - in built up areas in the south and west of the UK, they're fine outdoors stood in a sunny, sheltered spot - in an average winter, but not in a freezing one.

In colder areas, keep it in a sunny conservatory or bay window over the winter.
