We had a nice stay. We were greeted promptly by the building manager who was very friendly and professional. The apartment was clean and in a secure, modern building. The washing machine was very handy for those on long trips. The balcony was nice and it faces an interior courtyard. My only feedback for future guests is that the apartment is in a residential area and major sites are not easily walkable. It was our first time in Rome so we didn't realize how difficult it is to navigate. The heart of Trastevere is a 20-min walk. It's not easy to get a taxi in the neighborhood. I spent 1-hr trying to flag one down after checking out while dragging my 50 lb suitcase. The shower head is also handheld so that took a little time to get used to.
