Great location, lovely restaurants and fantastic walking distance from all major monuments!
The hosts sister, alessandra, was the person who we communicated with- and she was excellent! She organised us a chauffeur vehicle from the airport to the apartment, and us at the apartment to give us an excellent overview of the apartment and the best places to eat in the area. She was an excellent host and even let us leave our bags there post checkout time so we could do a morning Vatican tour!
The apartment is spacious and cool and a great location.
