The apartment itself is perfect - spacious, well equipped, modern, and clean. Our favourite feature was definitely the showers - they were AWESOME (large, clean, quick hot water, and good water pressure)! The apartment is located in a quieter neighbourhood, but there are a few excellent Italian restaurants within 500m. The hosts were easy to communicate with via the Airbnb app, and we met with Stefano, who was easy to get ahold of via WhatsApp. Stefano was also extremely gracious even though we were extremely late due to a delayed train/waiting for the H bus.
The experience at the apartment was great, however, our experience with Rome transportation via bus was not. The apartment is easy walking distance to both a bus & tram station, and we would highly recommend taking the tram. We found the busses highly unreliable & were forced to wait more than 40 minutes on two occasions where the tram/metro were not available. The morning we had a tour booked at the Vatican, we left the apartment 2 hours prior to the tour and made it with 5 minutes to spare. Please keep in mind this was in high season in Rome, and don't let it deter you from the apartment - it's just general knowledge for how long transportation can take you if you have pre-arranged times :) All in all, great apartment and great hosts!
