We didn't get a chance to meet Carmin, but a man who lives above her and runs a hostel let us in and gave us the keys. The room was perfect; everything we needed including a map to Rome. The building was directly across from Termini and it only took us 2-3 minutes to walk back to get our train. From the outside, we were a bit worried at first, as the building was quite dirty and run down, lots of youths were hanging out outside when we arrived around 8pm, and everything spelled like urine. I'm not sure if this is just Rome in general (we were only there for a day), but once you get into the room everything is fine, and we did feel rather safe after all. Thanks Carmin!
