The apartment: adorable, clean, spacious, and loaded with amenities. Great for a family or for a group of friends traveling together. The beds were very comfortable. The living room and the master bedroom had multiple entrances, so if you're looking to create more privacy between rooms you can close the doors and still have access to the kitchen and second bathroom without issues. There's a cute terrace with a class view of Roman gardens and building - like something you'd see in a Fellini film :)
The location: great! While you can't see the pantheon from the windows, it's less than two minutes away by foot. Pigna, the zone where the apartment is located, loaded with grocery stores, wine shops/enotecas, trattorias, and cafes. Because the apartment is located in the same building as the Pantheon Inn, I noticed it was a bit noisier on the weekends (I could hear some travelers laughing and talking one evening), but it wasn't anything that would prohibit me from staying there again.
