The apartment was as in the images, very clean and tidy when we arrived. The best feature is by far its location, we were able to walk to all the sights fairly comfortably (Pantheon, Colosseum, Vatican). Though there was some initial miscommunication on collection of the keys, Santi and Sonia were kind enough to offer reasonable compensation. Remember to place the WiFi dongle on the window sill to get a decent connection as it relies on cellular networks.
All in all, a very decent place in a great location with a responsive host in Santi/Sonia. Thanks Santi and Sonia.
