What a great space! As others have said, it's converted from what was formerly an exercise studio, so it has highly ceilings and other interesting features like a barre on one wall and walls of mirrors. They did a fantastic job of converting it into a very comfortable Air B&B apartment. There was plenty of space, a comfortable bed, nice shower (make sure you turn the hot water on first!), and great kitchenette. The location in the Monti area is wonderful; it's a fairly close walk from Termini, full of its own charm, and easily walkable to major Roman sites. There's also a nice code system, so you don't necessarily have to carry your own keys. We would definitely look into staying here again the next time we're in Rome!
