We cannot recommend Simona's place enough. Simona always responded immediately before our stay and (as others mentioned), she coordinated airport transfer which felt like a luxury since we were greeted at the airport and our driver knew exactly where to drop us. The location is unbeatable - we chose her apartment specifically because it was in Trastevere and we knew we would be able to walk everywhere we wanted to go. While we spent most of our time out and about exploring the city, Simona's apartment was just perfect in the evenings when we returned to regroup and relax for a bit before heading out for dinner.
Our friends who we traveled with were planning to head to north after our stay in Rome, but were concerned about traveling due to the coronavirus outbreak and Simona coordinated with them quickly to put them up for a few more days (in another one of her apartments), and they were extremely grateful!!
My partner and I are Airbnb hosts ourselves so it is always nice to experience the 'other side' as guests. We know how much work it is to be a host and applaud Simona for all of her efforts!
