http://www.trav.com/wri-5407/LilliputHostel/Reviews here's the review. It was a nice hostel, in fact I believe they have two locations. We were living in old appartment just 5 minutes from Termini. Staff is very nice, I just loved to have my own key so I could go in and out anytime I wanted without passing any kind of reception
