This apartment is absolutely incredible. It is like a modern art museum in this beautiful, old building. Just steps from the Pantheon, the location is historic, typically Roman, and it was the perfect home-base for us to explore the city on foot.
High ceilings (3m?), secure entry, private bedrooms, three bathrooms, and a large living room/salon gave our family of four plenty or room to gather together or find quiet space. There is a simple, clean kitchen but we ended up not cooking a single meal there - you're surrounded by amazing restaurants at all price points.
It is on an tiny side street, mostly-pedestrian, surrounded by shops and restaurants. Accordingly, the sounds of the city are always present but not unwelcomed.
The hosts are superb, thoughtful, guest-oriented gestures abound. We would absolutely return, next time for a longer stay...
