Rome is a sightseers dream, with ancient structures like the Colosseum and the Pantheon. It's also home to the Vatican City, which is listed as being the world's smallest country.
Rome is lovely to visit between April and October. Bear in mind that it tends to get extremely hot during July and August, when the beaches are very crowded. The weather can be unpredictable in December and January too.
The Rome Marathon (Maratona della Citta di Roma) is held in March, and from Maundy Thursday till Palm Sunday, Easter processions can be enjoyed. St. Peter's Basilica hosts Sunday Easter Mass, and on June 2 the Festa della Republica occurs. Visitors and locals are entertained with impressive military parades and events during this National Holiday. The Feasts of St. Peter and Paul are held on June 29 and there are lots of summer events and festivals, like the Rock in Roma event, which begins in June, and continues into August.
Prices are cheaper in Rome, compared to London and the UK, and you'll save on shopping and restaurant bills. Restaurants have a "coperto" or charge for the use of items including cutlery, plates and tablecloths and there's usually an extra charge for bread/grissini, although tips are not customary. "Coperto" is often referred to as "servizio" in Rome and surrounding areas. There is a no smoking policy in bars, restaurants and on public transport.
