Nicolo is an amazing host. He personally greets you upon your arrival (as well as personally says thank you upon your departure). There are many "special touches" that you immediately notice upon your arrival. He has a binder with maps of the area, directions for the buses and metro and numerous restaurant recommendations. He personally walks you through the apartment and shows you how to use all the appliances and answer any questions you may have. Upon request, he will also make transportation arrangements for you to from the airport/train station (I recommend you take him up on this).
His apartment was very clean and comfortable. There were 6 in our party and we felt "at home" during our entire stay. The apartment is located on the ground floor, so there are NO stairs to climb. The apartment is located in a residential neighborhood that is very safe and the building itself has a locking gate to enter. We felt safe our entire trip.
The bus stop was about a 3 minute walk from the apartment and the metro less than 10 minutes to walk. Both very accessible and convenient (we used both options during our stay).
I highly recommend this location and will definitely stay here again should I ever visit Rome in the future.
