Location is perfect. Campo di Fiori is literally behind the apartment. Piazza Navona is a couple of streets away. We easily walked everywhere. Trastevere, Jewish ghetto, Coliseum, Campo di Fiori, Piazza Navona, and Trevi Fountain are all within walking distance. Spanish Steps is a bit further, but still you can walk there (we did!). The apartment is clean, well furnished and very comfortable for the 3 of us. I think 4 adults can stay there comfortably. The 2nd bathroom is extremely helpful. The hosts were great. They organized our transportation to and from the airport. They were very welcoming when we arrived and gave us tips on where to go/eat. I highly recommend staying there.
