The location of the flat is really great for travelling and sightseeing. It is 10 minutes away from the Circo de Massimo metro, and right next to the Colosseum and Romano forum. I had no problems during my stay about going to the city center. It is literally walking distance away from the touristic sites, and great places like Trastevere, or other main squares.
The apartment was very clean, and Luca was a great host. He responded very quickly to all my questions, and checked with me during my vacation about how it was going. I would definetly choose his flat if I ever have a chance to visit Rome again.
