This apartment is a great place for bigger groups to explore Trastevere. It was hard to find a place to accommodate our group of 10, and this place does a good job, although it definitely feels more like 3 apartments strung together than one large one.
The apartment was clean and check-in was easy. However, the dishwasher was broken, which was frustrating for such a large group and was not as advertised. If you are especially concerned about privacy, do note that there are security cameras located in a couple of the apartment's common areas.
Overall a very good, clean, and safe choice for a large group looking to explore central Rome.
