We had a very good experience with our host. Although we did not meet him personally, he was very much in contact over the website to make sure we had everything we needed for the stay. His housekeeper gave us the keys, and we signed the contract and handed it in at his apartment the next floor up.
The location is excellent, its very close the the colosseo metro stop, and has apartments and grocery stores just down the street. There was a street party going on the weekend we were there. Andrea communicated to us that it would be going on, it was a bit loud, but we really didn't mind at all. The apartment is just as seen in the photos. Although the apartment has air conditioning we did not need it as there was a nice breeze flowing through the apartment once the windows were open. Great place to stay while touring Rome, i'd highly recommend it.
