Beautiful apartment, very close to public transport. Nearby train and tram lines within 5 mins walk. The apartment is essentially on the train line out to the airport which makes things easy.
Enrico was incredibly obliging and went out of his way to accommodate us. He checked with us during the stay and helped us with any issues.
The apartment is down the road from a large hospital so there is very frequent ambulances which are very loud. Don't expect to have windows open due to the noise. There are seedy characters and beggars around Trastevere station so be wary but the apartment is very secure and safe.
Highly recommend staying here if you are looking for somewhere just outside city centre.
