The property was as shown in the photos.
It is located in the inner courtyard of what appears to be an apartment/hotel complex, and the stairs down to the property entrance are private in that there's only the entrance to the Airbnb, so you don't have any people walking directly by the door. As it is located in the inner courtyard, you can hear people when they leave for work in the morning, but other than that, it is very quiet with no street noise.
It is located north of most of the tourist areas, but it is only a 30 minute walk to get to the Spanish steps, and an entrance to the Villa Borghese gardens are a few blocks away, which makes for a great relaxing spot to visit. Otherwise, its a relatively cheap and short taxi ride to visit the main tourist areas in the south like Colosseum, Vatican, or Trastavere areas.
Additionally, read through the Airbnb listing to find Fabrizio's guidebook! It will answer most questions you have about the area and has recommendations for local food and grocery stores! Highly recommend!
