The Chelsea Hotel is one of the most durable symbols of bohemian Manhattan. But lately, the atmosphere there has turned toxic. Last year, a real estate developer bought the Chelsea, and began renovations intended to turn the counterculture institution into a luxury hotel. Residents filed suit, alleging that the construction had led to health violations — and was really an attempt to push them out. After a court ruling in their favor this week, the remaining tenants still find themselves in conflict – both with the new owner, and each other.
