Base yourself in laid-back Greenwood, north of downtown Seattle, for access to a number of quality breweries, coffee shops, and parks, and stay in this second-floor apartment to return to the 1960s. Designed by the host, a residential architect and builder, it is a shrine to midcentury modern furniture. Pour a whiskey at the well-stocked bar and then migrate to the private rooftop lounge, where a Finnish sauna beckons.
