The process of check in and check out were very easy and convenient. Simona's brother, Massimo, met us at the apartment and gave us a tour of the facilities and explained how things worked in the apartment. he then spoke with us for a while to give us pointers on how to get around the city and which direction to walk to get to Vatican sites. He told us what bus routes come close to the apartment and how to obtain bus/subway tickets. He also provided a map and pointed out areas for eating and shopping that we asked about. He was very helpful and gave great advice. We had a problem with the apartment the first night. The refrigerator was not cooling at all, which we reported to Massimo and he got it taken care of less than 24 hours.
Massimo even got us a private car arranged to take us to the airport on the morning of our departure, at our request. Thanks for a great stay in Rome and we would certainly recommend this apartment to friends/family going to stay in Rome.
