I truly wish Airbnb allowed for half stars as this was really a 4.5 star property for us. We stay in many AirBnBs and reserve 5 stars for the exceptional ones. The hosts were fantastic and were very prompt with communication and very accommodating. This property is in a residential part of Rome, very few tourist, in a lovely neighborhood called Testaccio. It is a 15 to 20 minute walk on very good and safe paths to the south end of the historic area and about 10 minutes to Trastevere. About 30 minute walk to the Vatican. The apartment itself is large and well equipped. The kitchen was exceptionally well equipped. The Master bedroom has a very comfortable bed and a large master bath with a good sized shower and great water pressure. The sink area and the lighting in the bathroom were not great but certainly very usable. Air conditioning only in the bedrooms but good fans to move air below. Opening the windows worked to bring in air but the apartment is on the main square so, while the location is very convenient, its a bit loud at night when the windows are open.
The apartment has a lot of levels, only one flight of stairs but lots of single steps up and down throughout the apartment. We had a lot of trouble getting taxis to bring us to the area during busy times of day - even with Uber we would have many drivers turn down the rides - no idea why but we always found a solution, even if it took more time and several phone calls. Many good restaurants within 10 to 15 minute walk and a few within 5 minutes.
Overall a great property to stay in Rome, fantastic hosts and lots of room for 5 or 6 people. Only negatives, and they were minor, was the lighting was not great and the light switches were a bit hard to figure out, the noise from the Piazza at night could get very loud, the couch in the living room was not very comfortable and getting taxis to go to Testaccio was not always easy. Those were all very minor in comparison to the good location, spacious apartment, comfortable beds, great master bath and wonderful hosts. HIGHLY recommend.
