Location, location, location! This property is wonderfully situated to access main attractions - The Colosseum, Forum, Palatine Hill, Trevi, Spanish Steps, etc., all 1.0-1.5 miles walking. Termini Station is a 10 minute walk for public transportation. The best part is after a long day of site-seeing, the food options in the area are wonderful. Catch a short nap in the afternoon and then a short walk to dinner right on via Urbana or by the Opera House.
The staff is courteous and helpful. The unit we stayed in was well kept with a daily option to have cleaning come through.
To be clear, this is not a hotel in the traditional sense, but a set of condo units in a larger complex that are centrally managed onsite. You'll need to look at the doorbell console to find "Aenea Superior" (this took a moment to realize). We had a large 2 bedroom unit which held our family of 5 nicely. Like all old building, there are some sections of the walls that are thin and its possible to hear other units at times, but nothing beyond 11:00 PM really.
I would recommend this place and gladly stay here again.
