My sister and I had good communication with Rosanna. She let us in and showed us around the apartment, gave us recommendations, and was very friendly despite her very very limited English. However, this easy check-in was not the case for some of the other guests who checked into this Airbnb. Later that night around 11pm, other guests were trying to check-in but Rosanna wasn't there to assist them. My sister and I had gone to bed but were woken up by their doorbell ringing. We didn't know what to do, not comfortable enough to answer the main door to the building. After quite some time they were let in by someone (Rosanna's daughter maybe?). Their late check-in kept us up for a long time. Wasn't a very enjoyable first night.
Also, this Airbnb is more of a hostel. This was not what we were expecting so it threw us off guard. The apartment was kind of in a sketchy area but was manageable for the most part. It's in a pretty noisy area so the bars below kept us up into the late hours of the morning (I.e. 3am drunken opera singing). Aaaand wifi was spotty and kept disconnecting. On a positive note, this apartment is on the cheaper side and is close to Roma Termini!
