Luca is a wonderful host. He is a great communicator, we let him know that we wouldn't have phone service in Italy, and he accommodated us by giving us flawless directions and a backup plan so we would feel confident getting off the train and getting to the apartment safely. He told us which metro line to take from the Termini station, which stop, exact directions to the apartment, and his friend met us at the front door and greeted us by name.
The apartment building has a small elevator (we only ever used it to bring our luggage up and down), and is on the third floor (very tall stories). The building felt very secure, with a locked door from the street, a private courtyard, and a locked gate to the stairwell. Everything was very clean as well.
The apartment itself is better than the pictures. It was spotless, bright, convenient, and stocked with everything we needed to feel at home for a whole week in Rome.
The location is good for those who are able to walk about a half hour into central Rome (which we did everyday). It is close to the Vatican which was nice for going to the Vatican Museums (it's a five minute walk to the entrance). It is also very close to the metro line and a reasonable walk to a direct bus to the airport. There are many restaurants, cafes, grocery stores, and a market nearby.
Would definitely recommend and would stay again!
