Stayed here in early June 2021 for our honeymoon and it was great. The flat IRL looks exactly as pictured online, and is located in a bustling part of Trastevere. There are a TON of restaurants and bars in the neighborhood, so there's plenty to do. Further, you can get to the city center pretty easily via tram or walking. We were able to walk to the Pantheon in less than 15m and only used the tram sparingly. The neighborhood is young (think 20/30-somethings), but we enjoyed being somewhere with a buzz, despite COVID restrictions. Note that the flat is located above a restaurant/bar, that during our stay was pretty bumping. Still, you're on a high floor so the noise was manageable tho Italy still had a midnight curfew when we were there (we also used a white noise machine - it's a city so plan accordingly).
Fabio was super attentive and answered our questions. He had his assistant meet us for check-in, and checking out was super easy. Overall, a great place to stay in Rome, and easily a 5 star stay. If you like the idea of being in a neighborhood with REAL Romans, but with easy access to the city center, public transport, and near to both fun and travel necessities (convience store/atm/etc) then you've found the right place.
