The four-level Belle Époque palace, on Boulevard Victor Hugo in the center of Nice, was built in 1908 for a Swiss industrialist and his family. It now is divided into six apartments — each of impressive size — and the Zeidans have parts of three levels, including a large kitchen in the basement.
The second-floor neighbor lives in what was once the ballroom. The top-floor apartment, created from the reception rooms that were the artistic showpiece of the home, is on the market for 1.35 million euros, or a little more than $2 million. The other units, Ms. Connolly said, are each about 250 to 300 square meters (2,690 to 3,229 square feet) and worth nearly 1 million euros ($1.58 million).
