Location, location, location. It was a 15 minute walk from many major sights. In fact, we would walk back to the apartment in the middle of the day just to drop off stuff we had bought during the day and didn't want to drag around with us the rest of the day. It was a very quiet neighborhood, but right in the middle of everything. It's in a small apartment building which has an interior courtyard. In case it's not clear from other reviews/description, from an exterior locked door to the apartment building, you walk up one flight of stairs to the interior courtyard, then up another flight to the apartment. They are nice wide stairs, though, so no problem getting luggage up the steps. We would definitely try to book this apartment again if we come back to Rome. It was superb. And one more thing, we stayed for 2 weeks so storage for our stuff was important - there is an entire wall of (empty) closets in the master bedroom into which you can unpack. That wasn't clear from the pictures - the bedroom is more spacious than it appears in pictures.
