Carmen and Chris’ place was a fantastic spot in a great location that is walkable to almost anywhere you’d like to go in Rome. I would highly recommend staying here if you have the opportunity.
A few things to note: If you are taking a train in (to Roma Termini) I would recommend taking a quick and cheap Taxi ride, it will make your life a lot easier. Also, this is not a con but if you have a rough time sleeping on very firm beds you may want to be wary as this one is very firm.
