Comfortable place to stay - on the first floor, yippee! For a cab from and to the train terminal cost is $20 to $30 depending on traffic. The Trastevere is very down to earth area and you get to know the people. You need to take bus 8 to get to piazza Vincente to ride any of the tour buses. Lots of walking in Rome. Paola is a total sweet lady, very helpful
