Carlotta is a very friendly person, who takes of everything. We had a pleasant stay in the apartment, which location is very convenient about 5min from the Roma Termini by foot. Straight in front of the building is a bus stop that takes you close to the Pantheon, Castel Sant Angelo or the Vatikan.
One thing to note.. Although the apartment is renovated, the building is quite old and the apartment is located towards the atrium. So the connectivity was unstable switching between 4G and no connection at all. There was no Wifi present at that time. Also at time of stay there was no elevator in the building (3rd floor). That is in planning though..
