CONDO CRAZE

TENANTS resisting the conversion of Manhattan House at 200 E. 66th St. (once home to Grace Kelly) into condos blame it for the death of a 97-year-old resident. Martin Burwick, whose unregulated lease would have been up in April 2007, died of pneumonia on Monday, causing some activists to blame the stress of eviction. "A man is dead, and it's from the conditions in the building," one tenant said. A spokeswoman for Manhattan House, owned by Richard Kalikow and Jeremiah O'Connor, denied the claim: "We are all very sorry to hear about the death of the 97-year old gentleman. We have taken every precaution to ensure the safest and healthiest environment for the tenants."
