The Rome Popolo business centre occupies the second floor of the Palazzo Valadier, one of the city's most prominent addresses. The business centre overlooks Piazza del Popolo, a large pedestrianised square in the historical heart of Rome. Tourism is the predominant local industry, but Rome also attracts national and international companies from the energy, transport, technology and commercial service sectors. Rome is an important centre for the fashion industry, radio, television and film production. Its university is the largest in Europe and the second biggest in the world and the city is the base for many international scientific institutions. The Rome Popolo business centre is just a short walk from the nearest underground railway station, and half an hour from the Leonardo da Vinci International Airport.
