 In the early 1940s, during the Second World War, Hemingway's three sons often visited him at the "finca", sometimes staying in a small house that Martha ("Marty") Hemingway had fixed up for them.The guest house, a converted one-story wooden garage, is now used as offices for the museum director and staff and for meetings.They reported that the property then was overgrown with "manigua" and "flamboyan" trees, but that most of the rural land has since been taken over by housing.
