Nice place very close to Trastevere Station so great if you're arriving from Fiumicino airport. Gianmarco was really helpful and we were even allowed to stay a little later because the guest following was arriving in the evening. He even met us mid trip when we had a problem with our keys (our fault!). The area is nice too as it's actually a proper area with locals and not many tourists.
And, there is a 24 hour Maritozzi bar downstairs!
