Who lives here: Pietro Castagna, a Milanbased interior designer, spends weekends here with his dogs Enzo and Nina. Style of home: Built in the 1600s as a convent, the villa is located in the town of Bellagio on the shore of Lake Como. It’s been through several renovations over its lifetime, most recently when Pietro simplified the structure to create four apartments. Pietro purchased the property 10 years ago and spent two-and-a-half years renovating it. The renovation would have been quicker, but local rules prohibit renovating during the summer holiday season.
