Excellent location with the colosseum view and being right across the street and the metro being so close. The 24 hour market being a block over made it convenient for quick trips to the store. There are 3 flights of stairs (no elevator) which wasn't a problem for us. The one bed room is a twin/single bed which wasn't comfortable for 2 people but the sofa pulled out for 2 people. There is a washer but no dryer, but there is a laundry mat a few blocks from Cavour stop on metro. The toilets do not work as efficiently as they do in the US but eventually clear (so don't panic). There is a bar very close where the street is full after hours and can be loud if you go to bed early, but was not an issue for us.
Excellent time and would return again and again.
