We were very pleased with our stay at Marco's apartment in Rome. The apartment was clean and spacious. There were five of us staying in the space and we never felt cramped. The apartment was bright and airy. The building was clean and secure.
The hosts allowed us to drop our belongings off early and had the apartment cleaned throughly when we returned.
Marco was very responsive to our questions and fixed a minor issue right away. He also recommended a number of excellent restaurants in the area. The neighborhood is close to Vatican City and had many nice coffee shops and bakeries for breakfast along with a few 'mini marts' to purchase food and supplies. Many of the other sites in Rome required a 30 minute or so walk or a taxi ride to access (we did not view this situation as a drawback).
For visitors from the U.S., be aware that the apartment (as most in Rome) has a washing machine but not a dryer so clothes need to be line dried. We would definitely return again.
