We stayed in Jacopo's apartment for one week. It is a very cozy, clean and well-equipped apartment located in a quiet and safe street. Jacopo stayed in touch with us during our whole stay and always replied quickly to our questions. The Colosseum and the Monti Area are about 15-30 Minutes walking distance. However keep in mind that the Trastevere Area (where also a lot of restaurants and bars are located) is a bit further away (about 60 Minutes walking distance). We really enjoyed strolling around Roma which was why this wasn't a problem for us most of the time, you might want to look into public transport. In general, we can definitely recommend this apartment. Thank you for having us, Jacopo!
