It's difficult to make a list of all the beautiful things you can find in Rome. Among them there's Saint Peter square, surrounded by Bernini's colonnade, the basilica and its famous dome. The mysticism you can feel outside is nothing compared to the one you can sense inside, walking through the main aisle or the basement where you can find the remains of Saint Peter and the Popes that followed.
You could walk around town for weeks without being able to visit all of its beautiful sites. For those who don't have a lot of time on their hands, even just a few days, our suggestion is to go on one of the guided tours. Many agencies organize tour buses that, following a route with many stops, allow you to visit all the main attractions in the historical centre. For those who prefer the "do-it-yourself", you could stop by one of the many information booths around town and ask for a tour map and a public transportations map. It's possible to follow the same itineraries without being part of a tour group.
Together with the Colosseo and the Trevi Fountain, don't miss the Vatican Museums. The immeasurable artistic beauties inside are outclassed only by its flagship, the Sistine Chapel.
After paying a visit to the government buildings, the Quirinale and palazzo Chigi, your visit in Rome would not be complete without a stop by one of the Trastevere's trattorias. The flavours of the local cuisine are very intense and peculiar: they resemble the colourful nature of the natives.
