Very nice stay! Rosanna was a great host who met us late, left us snacks and soaps, and made sure we had everything we might've needed. We didn't see her much afterwards, but that was fine and she made sure we had total privacy. The room was surprisingly comfy even for three people, and although it got kinda hot during the Roman summer, it was manageable with the big window.
Also the location -- it's in the university district, so there's plenty of bars and young people around at night, which is fun, but the main touristy areas are a bit of a walk away.
