I regularly use Airbnb and this is easily the worst experience I have ever had. My room turned out to be directly above a bar with a VERY loud speaker system. The first two nights, I could hear continuous bass "thumpa-thumpa-thumpa" through the floor from 9pm until 8am the NEXT MORNING. I normally sleep through anything, but the shaking walls and floors from this all-night dance party were too much. On the second night, I awoke at 3am from the noise, then walked downstairs to realize that the bar had actually closed at midnight, but they apparently leave their music booming all night anyway. The hosts refused to grant a refund or transfer me to another room, and were essentially impossible to reach. For example, their phone number went to a message-taker who knew very little about the situation, and I was never able to get help from an actual human.
