The apartment is impeccable: clean, well furnished, well situated, well connected. The hosts were very welcoming, explained everything to us upon arrival (from the details of the apartment to the city life in Rome) and were always available if we encountered an issue. Overall, we had an amazing stay in Rome thanks to Maria Rita and Fabio :)
Unique point i'd like to mention: the apartment is next to train tracks. It can get a bit noisy early in the morning. But the windows are noise-proof, so with windows closed the noise isn't bothering.
