The communication with Federica was perfect and she was really nice and helpful. In general, the apartment was great and the bathrooms were really clean! Some towels and tableware were not that clean but that could be fixed well. The apartment has very thin walls and might be unsuitable for sensitive sleepers.
The neighborhood was great, especially the restaurant Radice and Eataly in the same street. Near to the apartment was the Train or Metro Station, so we could took to the train to the city (3-4 station to the Fontana di Trevi or Piazza di Spagna).
All in all, the quality and location of the apartment was good for this price!
