The apartment is charming and thoughtfully furnished, e.g umbrellas, a local cellphone, helpful restaurant suggestions, a washing machine, laundry soap, and a piano.
Sara was great. She arranged for us to be met at the airport (for the same price as a taxi), met us at the apartment and showed us how things worked in the apartment.
The apartment is very comfortable and conveniently located in a lively part of Trastevere. The building is quiet, but the street life is pretty noisy until late on Friday and Saturday nights. That is the trade off for being so close to a lively choice of bars and restaurants!
