When faced with a property with an impossibly hefty price tag we have to ask the question is it worth it? This one seems pretty promising. It's a 25-room red brick residence with 100ft of frontage along Park Avenue and situated between 64th and 65th Street in one of New York City's prime neighborhoods.The home was built in 1920 but has been renovated with new heating and air conditioning, a mechanical elevator, security and electrical systems. The home has southern and western exposures and views onto Park Avenue. There is a sunny yellow chef's kitchen and pantry, five large bedrooms, large formal rooms for entertaining, many staff rooms, a laundry, a wine room, a play room and space for a lavish home theater. Older touches of charm include the wood burning fireplaces, a marble staircase and hardwood plank floors. At $35 million, it's among the ranks of the most expensive pieces of real estate in the city.
