When we arrived, everything appeared fine but as we settled in we found a few concerns.
First, the house had not been properly clean. There were piles of crumbs on the furniture, the trash can was caked with food and smelled horribly, and no one had thoroughly cleaned the floors as there was piles of someone else's dog's hair in multiple locations.
Then we took a step into the side yard and things took a turn for the worse. There is a sign on the door that reads, "RODENTS WILL COME IN NEVER LEAVE OPEN." Then we went outside to find trash and dog poop all over. There was what appeared to be a broken hot tub covered in random construction materials and trash.
The dirtiness inside and outside plus the risk for rodents was enough for us to contact the host and Airbnb for a refund.
I spoke with the owner of the duplex and he was very kind and apologetic. I assume this was just a case of out sourced cleaning people not doing a great job and overtime things built up.
