LAP OF LUXURY FOR ZACCARO?

John Zaccaro Jr. is living in this apartment building, located next door to the YMCA in Burlington, Vt., while serving his sentence for selling cocaine worth $25 to an undercover policeman. Geraldine Ferraro confirmed her son is serving jail time in a $1,500-a-month apartment with maid service and cable TV but denied he lives in luxury and accused his prosecutor of trying to build his own political career around her son's case. ``We rented an apartment at the best price we could get,'' she said. Ferraro said her son cannot attend the YMCA under the terms of his house arrest, and the cable TV is part of the rent. As for maid service, she said, ``Once a week they change the linens.'' Zaccaro's prosecutor claims the conditions of the house arrest make a mockery of his jail sentence.
