This is the first time my family and I have ever stayed in a hostel, and Ostello Ave Gratia Plena was a pleasant surprise. The hostel is in a great location, about 15 minute walk from the train station and 2-5 min walk to shopping, SITA bus stop to Amalfi Coast as well as a number of great and inexpensive places to eat (we especially loved Arepa's for quick, tasty meals). What made this hostel truly special, however, was the staff. Everyone was friendly, knowledgable, super helpful and spoke fluent English. The staff went out of their way to ensure we had all the information we needed to make our day trips successful. Rooms aren't huge, but are more than adequate (we stayed in a private family accommodation - a room with 4 beds and its' own, private bathroom). The room, just like the rest of the hotel was spotless and well maintained. I would not hesitate to stay in this hotel again if I ever return to Salerno.
