We didn't meet Frank. His friend Armin was managing the apartment instead coz he works for the building. He was very kind and helpful. Our flight has been delayed, and I guess he waited for us there for some hours.
What we like: The apartment is located in city center, only 3 min walk to subway station which is only two stations far away from Roma Termini and many bus/tram stations around. There are quite many small restaurants, bakeries and grocery shops nearby. It was clean and the sofa was comfortable. There were many cute table elephant decorations LOL.
Some extra infos: The apartment is towards the street, so it's bit noisy during the night with open windows. We didn't find quilts and I contacted Frank. He responded quickly and he told us where they were. We found them bit dusty so we used towels as quilt instead. It was not a problem since it was very hot in Rom.
Generally it was nice experience with Franks apartment.
