what to do about harassing neighbors
Contact the landlord and let him know what’s going on. If they live below you, you could get some thick carpeting to block the noise. The landlord cannot evict you if you are doing normal ordinary routines and not playing the drums at 2am and having wild parties. You have the right to your own quiet environment and do not need to be told that they don’t like when you use your can opener or why you use the toilet several times a night. You need to let him know about the neighbors calling the police. They are harassing you. He may want them out or maybe they are the reason the apartment is always for rent. It’s going to be difficult living there unless some sound proofing is done.
