Excellent location, right on main street, close to travertines and tourist infrastructure.
Inexpensive rooms that are simple, but comfortable. Very clean. Comfy bed. Air conditioning! No divider between shower and toilet, which leads to water everywhere. Shower temperature fluctuated a bit, so you'd sometimes get bursts of chilly water. There were small ants around the door into the room that were interested in our shoes, but they never ventured into the room to bother us. There are several light switches for the room: our room had a dim orange "mood light", which was a nice touch, and you can control the light outside the room as well.
Run by older couple. Couple was friendly and helpful, though they seemed a bit impatient with us sometimes. Check-out time was listed as 12:00 on hostelworld.com, but couple insisted check-out was at 11:00.
Overall very enjoyable and would stay there again. Having AC and a private room for the price was excellent.
