WARNING - HIDDEN FEES
I had a stressful experience with Carmen. I was traveling internationally and her Airbnb was my first stop. My plane was landing at midnight in Rome. Two days before the arrival I messaged Carmen to confirm my arrival time only to be told that there was a 40 Euros late-night check-in fee. Nowhere in the listing, it specified a particular check-in window (Listing just said "Check-in after 2pm") nor did it mention any extra fees for late-night check-ins.
I was able to resolve this situation by contacting Airbnb support though.
Except for a stressful check-in experience, the place was nice and super close to the Vatican. Quiet and safe neighborhood.
Good stay just make sure you're not slammed with any last-minute fees.
