Mental note: next time I attend an international conference, every time someone mentions how nice it must be to live in Barcelona I will attach this piece as supplementary bibliography to my conventional answer (Americans Head to Europe for the Good Life on the Cheap). And I will also make sure to emphasize the last part of its subtitle: “Home sales to Americans have increased significantly, giving them a chance to enjoy a lifestyle they could not afford in major U.S. cities, but the influx risks upsetting local residents.”
