Houses. Apartments would mean I’d have to try my luck with the neighbors. A friend of mine has a neighbor upstairs that makes noise at all hours of the night. I’ve heard it. It sounds like his neighbor is constantly moving furniture.
My friend has asked the neighbor to quiet down, talked to the apartment complex about it, and even had to call the police to file a noise complaint one time. (My friend has young kids who might get woken up by the noise. That’s the main reason he’s concerned about it.)
