Sperlonga was the most beautiful and peaceful place I have been. I hope to return in a few months with the hope of moving there permanently.
Don't talk to strangers if you are a female. I met two Italian men in Rome who helped me to find the way at first and kept on taking advantage of me afterwards!
Look at Rome -- dirty, expensive, and crowded. It is the eternal city and there is so much to see and explore. And that is what every owner of a hostel, hotel, restaurant and every other business serving tourists knows. Convenient it is that most hostels and hotels are situated close to the Termini train station. It must be the cheapest area in Rome, because it is one of the most smelly, dirty, and -- for tourists, carrying their cameras and wallets -- unsafe areas. Plus, coming out of Termini, walking your first meters in the city, you will see homeless sleeping, be asked for money and cigarettes. The prices in Rome -- well, it is Rome after all, so every tourist is paying for it, but do yourself a big favor when you stay at a some hotel or hostel. Ask around what rate other guests pay, because you will be judged by your wallet and look by receptionists at many places at a difference of up to 60 €uro for a single room. Some tourists just pay everything.
I visited Terminillo in the 3 or 4 times in a summer several years ago and it was wonderful. Cool and lovely. One word of caution is don't go in August unless you really, really like crowds. The camping fields, the hotels and the bars are totally jammed. Have fun!
Rome is the most beautiful, busy, romantic city you can find. Do not miss it. Take the tours and walk as much as you can, there is so much to do and learn about it. Miss this city and risk dying unfufilled. A place designed for lovers and lovers of travel.
Most hostels in Rome are located near the train station. It's a very touristy area, but it's a reasionably central area in the city and it's nice to be able to walk directly to your hostel from the train station. If you stay somewhere not near the train station, there's also a metro stop at the train station, so you can usually get to your hostel that way.
