My family and I stayed at Monica's for a night on an extended layover at FCO. We arrived from the U.S. in the morning, checked in at Monica's by 11am, took a short rest, and then spent the afternoon at Ostia Antica (which is a great archaeological park and nice old town). Monica took care of our every need. She even arranged for our private transfer to/from FCO and to/from Ostia Antica (thanks Alessio!). I would definitely stay with Monica again if I was looking for a location close to FCO and would definitely revisit Ostia Antica.
