We stayed with Marco for one night and he was great! He was very easy to reach via text and email. We called when we arrived and he was on time to meet us. He is very organized with his check in process, had a list of places we could visit, a map, and explained where everything was in the apartment. There is air conditioning in both the living room and the bedroom, (a huge plus in my opinion) and a telephone (rare). Overall everything was just as described, and my mother and I felt very safe which was the most important thins. The flat is about a 20-25 minute walk to the Coliseum, and one street away from Roma Termini station (we rolled our luggage) which was super convenient to my mom and me.
