We thoroughly enjoyed out stay at this AirBNB. The host Sabrina was a proactive communicator and she was able to adjust our check-in process when we arrived early. She brought us through the unit, explaining how things worked and took us for a quick walk in the neighborhood, showing us the market and a couple good restaurants. The restaurants were special. You should definitely eat at Il Sorpasso which is one block away. Their food was incredible. We also ate at the restaurant below our bedroom window, Ristorante L'Eccellenza' di Corsetti in Borgo, it was also excellent.
The room was nice. It is large, with a foyer, full kitchen, living room, bathroom with a full shower, and two bedrooms. We barely used more than the bathroom and main bedroom. You could easily have two couples share this apartment. The furniture and decor was nice (but not amazing), it was very comfortable with a well-appointed kitchen, a washing machine, large flat screen tvs (although they did not have chromecast which would have been nice).
The location is incredible. It is near a major street and square so the taxi stand is <5 mins. St Peter's Square is 3-blocks west and Castle Sant'Angelo is 4-blocks east. There are a TON of restaurants and bars in the area. The neighborhood is upscale and felt very safe. We would definitely stay in this neighborhood and with the host Sabrina again.
