I would look further into hostel termini. I didnt stay there, I stayed at Allesandro Pallace (which I would recommend in a second) but it was by the downtown termini station. The significance of this is if youre traveling by train it is blocks from the main train station, and it is also the main subway station, and if I remember correctly the 2 subway lines intersect here, so you can get anywhere in the city from the subway within a short walk. being here means you can just get on either one instead of having to ride the subway to termini and then switching trains if you wanted the other line. so basically its the place to be. its not the greatest neighborhood but if you take a short walk away you can find some good areas. just mind the people directly around the train station, almost got pickpocketed by 2 little kids hanging around a seedy gang. just do research and you will find the right one for you... -kyle
