The room made me feel in prison even though it was very clean. It is well organized but very small and no view on the outside. Plus, it is a hostel, not a home. Lucia is nice but she lives upstairs and there's no common/living room. The room was very quiet and the bed of good quality. So if you're looking a warm and welcoming home in Rome, don't go. If you're looking for a clean place to sleep very close to the station, that's the one.
Note that the AC is not included and breakfast is one block away in a bar.
