<human>: Can you give me the gist of the text in a nutshell?

Some friends and I moved into a house a few months ago. We have parties on a weekly basis. We also care about being respectful to our neighbors so we walked around and spoke with them requesting that if they ever have a problem with us, they speak with us and we will absolutely remedy any problems they have.

This has worked out fine and we have a great relationship with all of our neighbors except one. The lady across the street from us has called the police on us for 'noise violations' several times around 9pm. Noise restrictions go into effect at 10pm here and we do our best to keep the volume at worst 'conversational'. No blaring music or anything like that. She has also called the police several times for parking violations. No tickets have been issued as no actual violations have been committed. The police have been friendly enough when they are here but it is obviously an undesirable situation.

I plan on talking to her with one of my housemates tomorrow but am not particularly optimistic (we did that when we first moved in). My question is: What should we do? She's harassing us using the police but the police have no choice but to respond when called. I'm not looking for revenge ideas or anything like that. I just want the situation to be resolved peacefully.
<bot>: Neighbor keeps calling the cops on us. Police don't see anything wrong and move on but it seriously brings down the mood of the party. What can we do?
