We had a very positive experience, very much due to the hostess who welcomed us and and made sure we had everything. We had quite a lot of luggage and since there is no elevator, it was quite a job to haul the luggage two floors up.

The apartment was clean and cool (aircondition was running when we arrived) so the first impression was quite good. Since it is very close to Pantheon there are several good eating places within walking distance and when on longer trips it is also very easy for someone who is not familiar with rome / speaks Italian to communicate to taxis where to go when returning home. The neighborhood is very quiet during night time.

When my wife's bag was stolen at a nearby breakfast place on the last day, the hostess allowed more time before checkout and a room to store luggage in, so that we could sort things out with the police.
