@Joshua804 The basic premise of refunds is that if you're unable to complete your stay due to major issues like missing amenities, safety hazards, or lack of access to the property, your host should refund you for the unused nights so that you can relocate. Airbnb knows that a huge percentage of listings are illegal and doesn't get involved with the policies of apartment buildings, so unless someone at the door is physically preventing you from entering, that's probably not a factor. Definitely mention it in the review, if the listing isn't explicit about guests being expected to lie.
You can try and get customer service involved, but they're slow and unreliable, so the likeliest result is drama. If you'd like to get out of this unpleasant situation and stay elsewhere, you may send your host a change request explaining that you're uncomfortable with lying to the neighbors. Ask for an earlier checkout date in exchange for a refund for the unused nights.
If you're just mildly annoyed and don't want to move, there's no kind of refund you'd be entitled to.
