We spent 3 weeks in Rome in January-February and had a fantastic time. The weather was not always ideal for outdoor activities, but there are so many indoor things to see and do that it is easy to fill time. Be sure to visit the major sights but also look around for some of the minor ones. There are numerous small churches with fantastic architecture, art, and histories, and there are almost too many restaurants and bars to try. Every neighborhood, or so it seems, has some often overlooked places worth visiting.
