Ketty's apartment was fantastic! The rooftop terras has an amazing view (you can see the San Pietro) and it is really nice to start or finish your day on your own terras in the sun, which is really cosy with all the plants. Off course, since it is on the 5th floor, you do have to walk a lot of stairs. So only book this if this is not a problem for you. The location is also great, within walking distance of Campo dei Fiori and Piazza Navona were you can find all nice restaurants and bars.
