Frank's flat is well located, next to the subway station and some bus stops, but also not that far away from some famous places such as the Colosseo, the Trevi fountain, the Pantheon...etc (30-40min by foot). The apartment itself is well equiped, modern and clean, even though it can be a bit noisy (it's in an animated area after all), and the matresses in the room could be a little bit softer. Overall a nice play to stay in to enjoy Rome.
