We had a good time at Monica‘s place. It is on the top floor of an old building without elevator and it had a nice city view from the terrace accessible via a stair from the living room. It is located near Piazza Navona with lots of bars and restaurants, which can get a bit noisy. There was a scaffolding at the building with some construction going on while we were there. The check in went very easy, and we had to pay tourist tax in cash, which has not been mentioned in the listing as far as I remember.
Overall a good place. Thank you Ambra and Monica.
