Living directly on Piazza Santa Maria Trastevere, with a view that looks out into the church, is an amazing Roman experience. I stayed in Francesca's flat for three weeks and highly recommend it. It is spacious, clean, artfully decorated, lively but also providing respite and pause from the bustling neighborhood. Of course, there are many great restaurants and bars and cafes within walking distance, and it is easy to get to center on foot or by bus or tram.
