Federico was an excellent host who would always respond promptly, and made us feel very invited. He even had a bottle of prosecco waiting for us upon our arrival! Federico also helped us organize our transportation to and from, which was a MASSIVE help.
The apartment looks exactly the way it does in photos, it's beautiful, and less than a 2 minute walk from Piazza navona. Great area with some awesome eats (the one Federico recommended ended up being the best one of the whole trip!).
Highly recommend, beautiful home, beautiful spot, and a very friendly host
