Roberto's place was actually even nicer than the photos (first time that's ever happened for us). It feels far more like a home than an Airbnb that someone has put together on the cheap. We were 2 friends traveling and used both the bed and the sofa bed. The sofa bed was very comfortable, linens and pillows clean and nice. We ran into a problem with the hot water, but felt like it was a temporary issue that will be addressed, so we're sticking with a 5 star rating.
We chose this place because it's closer to the airport than where we were staying earlier in our trip to Rome. We just needed it for our last evening. It's situated in a lovely neighborhood, has restaurants and a supermarket within a 5 minute (or less) walk. We wish we could have stayed longer & would love to return.
If you stay, we HIGHLY recommend going to Alleria for aperitivos. It's a short walk from the apartment, the food was spectacular and a welcome change from the standard tourist fare in other parts of the city.
