The historical and geographical centers of Rome are completely different things. Rome is a large metropolis in Italy with a population of about 4 million people.
Since in Rome 5-6 story buildings prevail, the area of the city is huge. The ring road has a diameter of about 20 km, and because of many narrow streets and the cultural tendency of Italians to do things slowly, in a relaxed mode, traffic jams and chaos are quiet frequent here.
You may lose a lot of time when travelling in Rome, so it is very important to choose the right hotel in a strategically good place to enjoy your stay in the Eternal City to the fullest, walk mostly on foot, and don't spend much time and nerves on local transport. Before the trip, it is important for each traveler to study a city map for at least 10 minutes in order not to find yourselves on the outskirts of the city.
On the map below, we have plotted the main attractions and central places in Rome that immediately come to mind. And even if you have never been to Rome, you've heard about them on history lessons or from movies - the Colosseum, the Pantheon, the Vatican, the Trevi Fountain, the Roman Forum, the Spanish Steps and so on ...
It is not necessary to be an excellent student in geometry to notice that the greatest concentration of sights is around the Pantheon. By the standards of Ancient Rome, the Vatican is at the outskirts, backyards of the city. Therefore, the phrase “We lived right next Colosseum” or “next to the Vatican” may sound cool when you tell stories to friends, but people who know the city just smile politely. This, of course, is better than staying at a hotel somewhere around a final metro station, which you can reach in 20 minutes by bus, which runs once an hour.
By the way, about the metro in Rome. The nearest stations to the historic center are Barberini (10 minutes walk to the Trevi Fountain), Spagna (Spanish Steps), Colloseo (Colosseum) and Ottaviano (Vatican Museums). Inside the most interesting part of the city, which is huge, there is no metro.
The most interesting area for us is between the Pantheon, the Colosseum and Trastevere, since it is here you can find those atmospheric narrow streets, as well as historical places and beautiful sights, every 10 steps!
