This hostel I really nice. It is safe inside, clean, spacious, and has a nice common area (although no one really used it). The staff were okay but not the most helpful. This is a less social hostel than others with no daily activities.
The rooftop bar was amazing and a great way to meet people. Good drink, good area, great view.
The area around the hostel was my biggest concern. I didn’t feel unsafe at all (as a solo female traveller) but it is definitely a worse part of the city because it is so close to the train station. All the main attraction of Rome are around 2kms away.
