We had a phenomenal stay. The apartment is located on the fourth floor with a balcony overlooking Piazza del Popolo, with easy access to the nearby Flaminia Metro. The main room has high ceilings and is very spacious, and there is a bedroom/bathroom with a lofted space above both.
The area feels very safe (the building also has a doorman), and has lots of excellent restaurant options. The host is very responsive and will meet you to help check in.
