The apartment is located in a great location, right on Piazza Campo de Fiori. It was great just stepping outside the door and having the market available at breakfast, or the restaurants on the Piazza available at night. There was definitely some noise from the piazza at night, but this was expected due to the description. It wasn't anything that bothered us since we had earplugs, and some of it was actually enjoyable (there was singing).
The apartment was clean and everything was in working order. The rooms were nice-sized. We had great communication from the host, who helped us with a problem we had at the airport with our pre-arranged transportation. Check-in was very thorough.
