What's the meaning of "overhead" in the sentence " The hotel's leafy acres and scattered buildings are laid out on Nairobi Hill, a world away from the overhead bustle of the city centre". Does it refer to air traffic? That's the only image it conveys to me but then, I find the sentence strange as it shouldn't only apply to "city centre" but to the city in general.
As always, thanks a lot.
It is possibly a typo - "the overheard bustle". Very likely if it is a brochure.
