Pacific Heights, San Francisco
Concierge.com's insider take:
Erected in the late 19th century, the elaborate Victorians here are now inhabited by millionaires. Notable houses include the Spreckels Mansion (2080 Washington St.), owned by novelist Danielle Steel, and the Haas-Lilienthal House (2007 Franklin St.; 415-441-3004), a restored Queen Anne Victorian. Enjoy the views from Lafayette Park and the steps at Broadway and Lyon streets, then head over to the ritzy Upper Fillmore for some shopping.
