Marco was an exceptional host and very accommodating. Check in was set for 3 PM but because I arrived way before that he arranged for his brother to meet me so that we could drop our luggage at the apartment. Everything was as advertised, centrally located to 2 bus lines and the metro line (all a 5-10 min walk away). Marco was also always available when needed as he provided the number for a cab when I called him as well as the names of about 10+ restaurants with addresses on a night when I chose to stay local. What was great was the restaurants weren't tourist traps and were frequented by locals giving you a taste of how everyday life is.
Most importantly the apartment was clean and provided all the necessities, I felt as this was my own place and welcome to anything.
I highly recommend this accommodation while in Rome. This has been my best experience using Airbnb.
