Nice and would recommend it for the price.
The room was what we were expecting. It fit two adults, it was clean, and it smelled nice. The shared bathroom was good and we were never waiting to use it (we were getting up later than everyone). The stall was small but my showers were quick.
My only watch out, and this has nothing to do with the place itself, is that the main train line was not running while we were there and it really affected us getting to the airbnb and then getting around. This could have easily been resolved by the host letting us know beforehand that there were issues and providing tips. We did learn on our own how to manage with the buses which were about 10 minutes away.
While were close to the colosseum, the rest of the neighborhood was kind of quiet late at night with not that many places open late to get dinner and drinks.
