We had a very nice 3-day stay in Rome. Marcella's place is very nice and clean and located in a quiet area. It is close to Roma Trastevere train station with train directly to Fiumicino Airport. Marcella is very helpfull. Communication in english is good and we had a lot of guidance and suggestions for what to do/see in Rome. 30 minutes downhill walk to the city center (- and of course uphill when you have to get back) - we didn't use bus, tram or metro at all during our stay. Only train to/from the airport.
