Since the beginning, Marcello was always very responsive. The place is well located in the heart of the Trastevere neighborhood, and within a walkable (~20/30 minutes) distance from the locations you will undoubtedly visit in Rome - including Vatican City. It is a central street in Trastevere with many bars and restaurants, so it can be noisy, but nothing sleeping with an earplug would not solve. We recommend staying there!
