Nick's apartment is very spacious and a bus that goes to the city center leaves right in front of the door. Supermarket is across the street and there are a lot of other shops around. The neighborhood (trastevere) going towards the river is very cool, lots of nice restaurants and bars. The apartment is right at a busy intersection, but with some earplugs you should be fine. One last thing: definitely follow Nick's advise about going to the keyhole of Rome, it's so beautiful and the pizzeria Remo close to that is very tasty and fun for affordable prices even for college students. We had a great stay in Rome!
