For a dozen years, Michael Davis has tested the patience of his neighbors at the tony London Terrace Towers in Chelsea. He has made life miserable for residents of the 1,670 apartments at one of Chelsea's classiest addresses. His litany of alleged bad behavior includes: Roaming the halls half-naked; Having sex with a homeless man in the building's health club showers; Blasting music and slamming doors; Stealing clothes from the laundry room. Now, Davis - who blamed some of his alleged transgressions on misunderstandings and sleepwalking - is getting booted.
