Carlo’s place is a great location! Maybe a 10 min walk to the Vatican or less and a 20 min walk to the colosseum, trevi fountain and Spanish steps! Carlo’s and his son were so kind and very helpful! They waited for us to get to the apartment and helped us up, showed us around the place and then showed us a map of all the major sites, buses and restaurants were! They left us snacks and coffee as well! The apartment was super clean and very homey! :)
