This is a comfortable and inviting apartment that is perfect for a family or a small group of friends. There are indeed three separate bedrooms with doors - no beads, false walls, or common spaces considered bedrooms. There are two full washrooms/bathrooms/lavatories, depending on your lingo. The kitchen is modern, clean, and well-appointed. You can actually cook here, if you want. There is a large central common area that is a combined dining room and entertainment area. The furniture there is comfortable, clean, and modern. WiFi access is easy and has strong signal. Air conditioning is also very comfortable. The washer/dryer takes some guessing if you are from North America, but the appliances are solid and do their jobs.
The location is in a rather quiet neighborhood, with many families, diplomats, and regular folks. If you want bars and nightlife and a scene, this would not be your choice. If you favor a quiet night of sleep after such activities (and others), then this is for you. There is quick access to the tram lines at the Buenos Aires station as well as easy bus routes into/out of the central city. There are a few nice, small bars and cafes in the area for your morning jolt and bread. There is a street market that runs Monday-Saturday along the back side of the apartment. They will start waking you up around 6:30 or so but the cosmic trade-off is you get the best veggies and fish before the locals show up. You won't notice them anyway since you will be out and about yourself (plus, the market is not that loud and usually quiets down by around noon).
All in all, this is a wonderful apartment in a quiet but still active part of town with easy access to other Roman activities. The place is as described and is clean and comfortable with quiet nights for sleeping and enough bustle to get you going in the morning to see more of Rome.
I would book again were I to go back to Rome.
