This neighborhood-based, below ground level room was clean and comfortable for a short stay. Large bed with comfortable feather comforter was warm on the chilly nights I visited. Kitchen alcove with hot plate was just enough to make coffee and reheat left overs. Fast and reliable wifi. Also an abundance of information regarding the local area including restaurants, attractions, and tourist books. Plenty of clear instructions for house rules. Roberto met me to let me in and complete paperwork. Thank goodness, because the check in instructions were a bit complicated for me and my uncharged phone (needed cell to connect to wifi to open front door to get to apartment and keybox). Roberto was also kind enough to let me store my luggage for an extra couple hours on check out day. 10 minute walk to nearest subway station. 20 minute walk to Termini (main train station), taxi was €10.
The only thing I would have enjoyed based on my personal preferences was natural light. Because of the apartment being located just under ground level, the single window that opened to the sidewalk didn't let any light in.
Overall, a good value for my couple days in Rome.
