This apartment really IS within walking distance of the top sites, including both the Vatican and Colosseum (if you like to walk!). Even better, there are good cafes, restaurants and shops super close by (Baylon was a favorite). The kitchen is legit if you like to cook. Tram and bus provide easy access to farther destinations or out of town. The host met us at our preferred time to let us in. People say the neighborhood is noisy at night; however, this apartment faces an inner area, not the street, and is pretty quiet. We took the train straight from the airport to Trastevere, and then the tram the rest of the way. Easy walk from the tram. We don't speak Italian, but it was doable . (TIP: We had a lot of trouble finding a tram ticket after getting off the train. These seemed to be optional, we later learned, which is presumably why no one near the tram stop knew where to buy them - at the tabacchi store.)
