Very nice apartment. We were a group of 8 and the apartment had plenty of room for everybody. Well located with a supermarket next door, restaurants right there, and public transportation and taxi stand also very close. Just to bear in mind that it is in a 3rd floor without an elevator, which we knew ahead of time so no surprises in that regard.
Maria was an excellent host, got in touch with us well in advance, offered to arrange transportation from and to the airport, she was right there for the check-in, showed us the apartment and gave very good tips of nearby services (supermarket, food to go, restaurants, taxis, etc). We had a late flight going out from Rome and she allowed us to keep the luggage at the building after the check out time. She was available all the time!
