Beautiful apartment with some of the nicest furnishings I've seen in an Airbnb that really allow you to absorb the culture of Rome. The surrounding area (Trastevere) has plenty of restaurants and bars to visit giving you plenty of options throughout the day and evening. Sara also initially reached out to us and provided plenty of additional details for our stay and even offered to make transport arrangements from the airport, contact a city tour guide and even an Italian teacher via Skype if we wanted. Her colleague Filippo greeted us at the property and spent a good 30 minutes showing us around the place and providing us with some very thoughtful welcome gifts.
As for the noise levels which I see other guests mention in their reviews, for me personally there were no major issues (we slept with the windows closed). The area does have people outside walking, talking and drinking which are typical noise levels you would expect from a main road, Saturday night being the most bustling with the other days of the week being much quieter. There's no loud pumping club music or anything to me that I would consider disruptive to sleep. If you are someone who is sensitive to noise levels when sleeping, then fresh earplugs are also provided for each guest.
One small thing I will mention is that at the time of this review, one of the double beds is two single mattresses and not one double but this is only minor and does not reflect on how well the rest of the property is furnished.
I would definitely recommend this to a group looking to stay in Rome, and would be happy to return!
