Sixteen years ago Rosana and Edward Chermisqui left Brazil and moved to Beverly Hills, Calif. A few years later they bought what they thought would be a starter home. But after raising their two boys and making lots of upgrades, the Chermisquis are still there. Now the couple is finally ready to trade up, and this time they're searching for a home with a few more amenities--things like an entryway, guest bath and an open floor plan for entertaining. And they definitely want to stay in Beverly Hills! Real estate agent Laurent Bertet will help them with their hunt.
