Ended up leaving after one night and getting a full refund. First we reported directly to Stella that there was mold and a cat in the apartment which wasn't noted in the listing (I'm allergic to both). Despite confirming these issues, she became hostile and refused to cancel our booking. She asked us to take her word that she would give us a refund if we canceled but we were firm about following instructions listed on the AirBnb website. We eventually called AirBnb customer service after she began to threaten to give us less of a refund for not cancelling, saying we were keeping her from others being able to book- she did not care about the mold! Luckily we got a full refund from AirBnb when they read through the host violations in our chat.
