The graffiti on the outside door was beautiful, and unnerving to us newcomers. But we NEVER felt unsafe here. The cleaning crew greeted us to let us to store our luggage before check-in so we could begin exploring, which was great. When we returned, the apartment was really clean and set up with little treats and conveniences. It's a cool space, convenient to some of the best food Rome has to offer, but popular as Trastevere is, it does get really noisy at night. Also, those big beautiful windows stay brightly lit until 444am. I recommend you bring a black out mask and ear plugs, and enjoy everything the area has to offer in your waking hours.
