Christine Eisner practices what she preaches. From the watery blue-green color scheme to cozy furniture arrangements, her new penthouse in Longboat Key Towers affirms the theories expounded in her Comfort Living: A Back-to-Basics Guide to a More Balanced Lifestyle. Eisner’s business, Lifestyle Design, focuses on how people experience their living spaces. "It’s not about things being perfect, and not about the cost. It’s about quality of life and balance. I call it design for your soul," explains Eisner. Why did she and husband Dean choose Sarasota? "For the good life," she says, pointing to endless Gulf views and Dean telecommuting from a terrace lounge chair. "This is our little slice of blue heaven."
