The location is 5 stars, we were within 15-30 minutes walk to almost every major attraction in Rome. A lot of activity in the Piazza which made it really fun without being a bother to us. The apartment had double window to minimize the noise which allowed us to have a peaceful rest after a long day. The AC worked perfectly well and kept us cool and comfortable during our stay.
The host was very accommodating and continuously checked on us to ensure everything was good. She even let us check out later than the usual time since there was no guest arriving after us.
I would only caution elderly folks as this requires you to go up quite a few steep steps to the apartment.
