We've stayed in a few Airbnb apartments and Simonetta was one of the best hosts- answered emails promptly, arranged transfers to and from the airport, left lots of info on the local area, even came to the apartment at 8am on a Sunday morning to check our car to the airport had turned up and we had enjoyed our stay.
Apartment itself was very clean and had everything we needed. The highlight was the terrace which we enjoyed every day given the fantastic weather.
The location is excellent- we walked to all the sites in 20-30 minutes; even the Catacombs was only about an hour's walk in the sunshine. Trastevere is ideal to stroll around in the evening with lots of lively bars and restaurants- ate in the square outside the apartment too which was very good. But no noise in apartment at night and no trouble sleeping.
We are a family of four (kids are 9 and 12 years old) and would recommend the apartment to any couple or family. Thanks again Simonetta- we will return!!
