Immediately once we entered, we found several bugs throughout the house: floor, ceiling, bathrooms, in the beds, both dead and alive. Since we arrived late at night (~midnight), we decided to tough it out and look to resolve it in the morning. We contacted both the owners and airbnb support but we did not receive a response from either whatsoever. That's not at all what we would expect from a superhost. We have several pictures of bugs we spotted, but there were plenty more we didn't capture because we attempted to remove them and didn't realize it was such a large issue until midway through inspecting the whole house. One of our party even slept on top of some bugs and only found out in the morning! We're curious as to what the cleaning fees for previous renters went to because all bugs we found were in highly visible areas. It's surprising for us to see all previous renters rate such a high cleanliness because this immediately made us question the cleanliness of everything else in the house. Additionally, the air conditioning did not work at all (thermostat had its batteries removed), despite being stated in the description, and it made the one night we stayed very uncomfortable.
As a result of all this, it completely disrupted our vacation. Our entire first full day in Nashville was spent finding another place to stay and paying a premium for the second place as a result. It put on a damper on our whole trip.
