Arianna Huffington is on the hunt for an apartment in the Big Apple. The move will allow the author and founder of the Huffington Post to spend more time with her daughters, Isabella and Christina, and at the HuffPo’s Manhattan headquarters. Isabella graduates high school this spring and will join her older sister at Yale this fall. Huffington is looking for an apartment near her Web site’s SoHo offices, but will keep her Beverly Hills home.
