Our first time in Rome! We walked from the train station, it took 20 minutes.
Overall, the apartment exceeded our expectations. It was clean and Luca had set up the bedrooms as we had asked. The location turned out to be ideal. The reviews from others are accurate. For departure our host arranged for a van (we were 7 with luggage) to pick us up at 7:00am and drive us to the airport. Our driver was on time and the cost was very reasonable, certainly less that it would have been for us all to take the train.
The best recommendation I can give is that everyone in our group loved the place and all would stay there again.
