I may be missing something here, I'm not sure, but I would have thought that being someones neighbor is a temporary thing, so I used está and was marked wrong. Could someone enlighten me please? Thanks in advance.
I keep getting this problem, where a group of people of unknown gender is given the feminine gender. In this case if she was the neighbour of a group of guys who were sharing a house would it not be 'Ela e nosso vizinho'?
