Andreas' place is ideally located just a few metres from Campo de' Fiori. The house and the apartment have a lot of character and are modern where you want modern (kitchen, bathroom, air conditioner), vintage where you want vintage (wood-beam ceiling, worn travertine steps, view out the shuttered window). Because this is a popular area, the street can be very noisy at night: it's too narrow for cars but obviously not for hordes of drunken tourists. So be sure to bring earplugs. The Campo itself is a joy and I recommend visiting the Forno bakery as well as the Farnese cinema. From here you're within walking distance of any number of key sites (Vatican, Navona, Pantheon, Trevi etc etc) and if you're not a walker there are also several bus lines that run along the Corso. I felt very much at home and would gladly stay here again! With my awesome earplugs!
