The place is very similar to the photos, maybe a little smaller in person. Since the building is very old, there was a very strong musty smell. The courtyard in front of the room is only shared by one other apartment, however, we were a little weirded out by the fact that the front door to the apartment was a glass door with a very see-through curtain covering it. Although it was unlikely that someone else would be walking through the courtyard and would look into our apartment, it didn't give us the best sense of security.
Lucia was helpful with two separate mishaps we had. She was very flexible and allowed us to check in early as well.
Overall the place is fine if you want something more unique, close to the metro, and a more authentic stay in Italy. However, if you're looking for a more modern, slightly more comfortable stay I would look elsewhere.
