Pierre was very hospitable and gave us the lowdown once we arrived. The place has a unique personality, the location is great if you want to spend time in a young, vibrant neighborhood of Pignetto which is down the street. We enjoyed meeting other travelers and the common space gave us everything we needed to cook and eat breakfast. The room was a little cramped for what we are used to and there is no AC so it got a little warm during our very warm Rome stay, although the fan and open window helped. The bathroom was what you expect for 6 people using it daily but that was OK. However, you should know that using the shower was very funky and awkward for me (5'11'') and water pressure was dissatisfying. I imagine some people would dislike this.
With that said, this is a great hostel for anyone that wants to explore Rome in a chill area near the Rome Central Train Station. Thanks Pierre!
