We stayed 3 nights at Roma Hostel and really enjoyed it. The accommodation is very clean and calm. I can highly recommend it. The location is also very nice, it's not very far from the main train station (Roma Termini) nor the sights like the Colosseum. We could walk pretty much the whole time. At the check in and check out we also didn't have any problems at all. Thank you very much for making our stay so comfortable!
