X things to know about Rome

Rome is a city of ruins, churches and baroc squares. the guides also speak about Vatican, Fontana din Trevi and other two, three maybe ten big touristic attractions. Thousands of other little things can make a trip to Rome richer.
Walking around the city. Rome is big for thousands of years. As the old romans, you could have a walk near the Imperial Fora, starting from the Colosseum and Constantine's Arch, to climb, then, the hill to Domitian's Imperial Palace. Look at the Circus Maximus. An amazing panorama! Don't forget about Via Appia Antica. So beautiful, by sunset!
Rome is the Vespa city but it's more beautiful if you see it by bike. With only 11 euro, uou can rent one for an entire day (more on http://www.ecomoverent.com/) and you can go from downtown to the outskirts, on the Tiber's banks.
No need to talk about the big piazzas, they are in all the guides. My favourite is Piazza di Spagna. The little squares, though, have a special scent. On my list: Campo dei Fiori, downtown, near Piazza Navona, from where, on a very narrow street you can get to Piazza del Fico.(now in refurbishments)

In that area too is Piazza di Pasquino, where you could go by day, to read what are the roman citizens complaints. For five hundred years, people come here to tell what bothers them, in verses or prose, on little notes called pasquinade which they attach to a statue. Conceived in the roman dialect, the little tirades generally attack the Pope and the governants.
Coffee, coffee and coffee again. Tip: if you drink it for the daily caffeine dose, you better ask for it at the bar. A ristretto vanishes in two seconds on the addicted's throat, so no need to pay almost the double price, just to sit at a table. Attention: the romans are drinking cappuccino only in the morning, so don't ask for it at noon or worse, in the evening. I am not claiming you won't be served, but in Rome we behave like romans, no? Ask for a cornetto near the coffee. Or for some aragostine ( filled with Nutella). For a richer sensation, I fully recommend the sorchette. They can be found near Porta Pia. The translation is vulgar, the pleasure not. A puffy dough with a chocolate and cream icing on top, the sorchette are famous around the students that spend the weekend nights in the clubs near Porta Pia. It is a real custom that before they go home, they fill themselves with these goodies, from the la Lambiase. A proof: the dozens of cars parked near the building.

Rome is the city of angels. On the walls, on a bridge that is only theirs (Ponte degli Angeli), in the churches, everywhere you can see the beautiful creatures that are watching upon us.
Caravaggio without a cue. Possible! Just go to the Saint-Louis des Français church, between the Pantheon and Piazza Navona. Three works of Caravaggio, all consacrated to Saint Matthew cand be admired in the chapel that bears the same name.
You can discover another Rome if you go to EUR, the quarter the fascists built in the 30's. Few tourist know about it, but, if you have time, you can go there to see how the architects of the early XX century saw things, then. If you get there, you could see the Collosseum in a square variant.
At table: waiters in Rome are generally rude, so don't take it personally! You cannot leave Rome if you haven't tasted the Italian wines . If you want to try something not so expensive, go to the Enoteca Cul de Sac (73, Piazza Pasquino) and wait for a free table. To the ladies, I recommend a Braccheto d’Acquim, because it is sweet, bubbly, and not so alcoholic. The enoteca menu consists of hundreds of wines from all over Italy.

all this wouldn't have been possible without Silvana, Andrea, Dana and Poliana. Mille grazie a tutti!
