Overall we loved our stay in Rome and this apartment was located in the perfect spot. Eva was so kind and helpful and we were able to drop our bags off before check-in as our flight got in about 4 hours ahead of when we should have been able to. The apartment is very quiet regarding the noise from Campo di Fiori, we couldn't hear any noise from the square. However sound insulation for inside the building is next to none-the restaurant has a closet right by the front door and every morning and evening (like 11:30 pm) we would hear them going in and rustling, dumping glass bottles etc and they always slammed the front door-which is heard very clearly. Aside from that annoyance Eva was great about handling some unexpected construction which woke us up our first few days. Overall, it's a great place, very clean and comfy with great TV, heating/cooling unit. But be mindful if you're a light sleeper like I am that the slamming doors reverberate very loudly.
