My wife and I stayed at Simona's apartment for a few days during our honeymoon and we really enjoyed our visit. Simona met us at the front door, provided us with a few suggestions for food in the neighborhood, and even hooked us up with a recommendation for dinner that evening at a place she loves. The apartment is in a great spot at the edge of the historic district, near the river, and directly across from Vatican City. Just a short walk east takes you to the Piazza Navona, Pantheon, and Trevi Fountain, while a bit of a hike can take you to the rest of the tourist highlights. Getting to the apartment from the train station was also fairly easy with the directions Simona provided which made our longer trips and our eventual departure that much easier. While we really enjoyed our stay, the only issue was with the water heater that was having problems when we arrived (apparently due to previous visitors pulling on the bottom cover). This did not really affect our trip (since we still had hot water) but is a good reminder to treat the places you stay with respect so that they can be visited and enjoyed by the next Airbnb-ers.
