It's a compromise for efficient living closer to centers and more affordable to other forms of housing in the same location. But you also have to deal with other people (more) than in other forms.

Sounds like a "your apartment" problem. Besides rent none of that applies for my apartment. Laundry room politics??? Each apartment has their own washing machine here.

They really need weight and age limits on upper floors. So tired of fatass Mcgee and his unhinged kids playing hopscotch with Danish clogs on day and night.

Actually I'd want you to go on.

Those seemingly universal issues with management, landlords and rents could be lessened by more co-op housing, I'd also contrast those issues with HOAs in suburbs.

Relations with neighbours depend on what kind of issues exist and general social net of a given area. People might complain or argue less when the social stratification doesn't hinder the access to their needs.

ACAB.

Hallways are sacred. Blocking hallways is a fire safety issue and should be dealt with proportionally seriously by the inhabitants. Asking the neighbours with clearing the hallways creates interaction and teaches mutual care and consideration. Anything else could be escalated.

Laundry room politics is a landlord and tenant protection failure, tenants have a right to affordable clean clothes IMO.

I'd also argue that apartments have a bunch of advantages for a city as they provide density-related infrastructure for better mobility (i.e. public transit, shorter travel times), better access to consumption and jobs et cetera.
