Castro Pretorio is a residential district that’s fairly central but has the advantage of being calm and quiet at night. Worth visiting in the area are sights such as the Porta Pia, the Church of Santa Maria Degli Angeli and the National Library. By renting a holiday apartment in the area you'll benefit from great connections with the public transport, with links to the metro and the central railway station, Roma Termini. An ideal area if you’re fond of relaxing at home in the evenings and sightseeing during the day.
