My wife and I had a great stay at Antiche Residenze- Pantheon. The 5th floor newly refurbished apartment in an old building with elevator is actually better than presented at the airbnb site, with an interesting view to fronting palazzo. It has everything a traveler might need, including adapters for foreign plugs. Location at Via del Collegio Capranica is excellent, two blocks from the Pantheon, and you can walk on foot to most Roman attractions. Simona from MITTO was quite helpful and considerate. We would definitely return, and recommend it warmly.
