The situation with the noisy neighbors was a rare exception to what this neighborhood is usually like, and even though it was out of my control since it was still only 5 o'clock when the noise was happening (which isn't against any rules) I still called the local police and asked them if they would talk to the neighbors about excessive noise which they did. I felt like the problem was fixed and I don't see why a guest would hold that against me after it was resolved.
In addition, there's no way the place could be considered run down since the main entryway to the neighborhood was repaved two years ago, all the buildings were repainted about a year ago, and the condo itself was renovated with new walls, floors, and appliances just 4 years ago. All pictures of the place were taken 6 months ago when I first started hosting on AirBnB.
What was even worse about all this is that I had no idea that Brandon was having a bad experience since all the problems seemed to be resolved and he was civil in our texts at first, but then when I refused his request for me to drive out over 30 minutes to return some pillows that Brandon left behind and asked him to come pick them up instead he blew up on me and started saying how horrible the place was and how he was going to leave us a horrible review. Overall though I think I handled things well and I don't think that there was anything I could have done better for this guest without better communication from his end.
