The room was fine. The location is very near the train station, lots of shops and restaurants near by. Pretty clean rooms as was the bnb in general. The room had a small desk and chair, closet space, and a little view over the street- enough room for your things- and a small bathroom. As others have said before, there is street noise but I think that is inevitable in Rome and you will hear other guests which is probably inevitable for a bnb.
Really the only problem we had was the kitchen. It was extremely small and shared by everyone and not stocked very well at all. One of the reasons we like Airbnbs are the kitchens so this was really disappointing. So if you plan to cook I wouldn't book this airbnb, however it is a pretty convenient, clean airbnb right by the train station.
