Federico's place is a pretty good option for your stay in Rome, especially if you just want an easy-access home base while you travel throughout the city. It's about a 15-20 minute from the Colosseum, but most other attractions throughout Rome will require walking much farther. Federico's place appeared very much as described and was relatively easy to find. I would recommend this Airbnb if you don't mind not being right in the city center and sharing a bathroom and kitchen with other potential guests.
