Simone was there to let us in and show us around the apartment and how to use everything. He also gave us a map and suggested places to go and where good walks/attractions are. He was very helpful and knowledgeable about the city and area. He was very responsive. He organized a taxi for us to go to the airport which turned out much less expensive than our planned alternative.
The apartment was spacious and clean. First floor apartment (although there are some stairs). Very close to the Vatican. Good walks near the apartment.
