Giulia's team is extremely nice and helpful. Our flight was canceled very last minute due to the weather condition and we had to change to another flight. Guilia await us till to the mid-night.
The apartment is right next to Colosseum, so, i won't say its walkable distance since it's just few steps. And you can find everything you need nearby: the metro, the 24hrs supermarket, restaurant and bars...
We had a great time with Giulia's team during our stay in Roma.
