we really enjoyed our visit at Agnes place. The location of the apartment is amazing and one is able to explore Rome completely on foot. The neighborhood was really lovely with restaurants, supermarkets and everything you need just around the corner. The best part of the apartment was definitely the roofterrace with a stunning view. Agnes was very helpful during our stay, communication was super easy and smooth.
The only thing one should keep in mind is that it is a charmingly old house, so you could definitely hear (at times) noises from neighbors or the hallway...but we got used to it pretty quickly :)
