I lived in Trastevere many years ago and was familiar with via del Moro and all parts of Rome. Therefore, I am not the typical American tourist to rent the apartment.
IIlaria and Elena were welcoming and always helpful, though we did not need anyone to show us the neighborhood. The apartment was absolutely gorgeous, looking exactly as it had in the photos, (which is something that does not always happen). All five of us fit in perfectly. We knew that the streets of Trastevere were noisy, but did not expect the extent to which big gangs of people congregated every night on vicolo della Renella which was next to our bedrooms. We thought it would be noisy in summer, but not so much in December; however, the shouting from these people continued almost always until 3 or so AM. They were mostly Romani, not tourists, so I guess summer tourist season makes no difference. Nevertheless, we loved the place. I would recommend it to anyone but would have to mention the noise.
