We had a wonderful experience at Marzia's apartment. Marzia was out of town when we stayed, so we ended up having the whole apartment to ourselves. We were met by her friend and he showed us all we needed to know and left us the keys. The apartment itself was great. The coffee and tea that was available to us was a nice touch. Marzia, even though she wasn't there, left us a wonderful note describing the neighborhood, a list of her favorite restaurants and cafes, and even a map showing us where they were all located. Pigneto is not in the city center, if that's what you're looking for. But getting there was very simple via the public transport. Took about 20-30 minutes depending on traffic.
Marzia was wonderfully communicative before and during our stay. She even called a cab for us to be picked up from her house (since our Italian isn't good!) while she was on her own holiday! Definitely recommend.
