Book. This. Apartment. I have stayed at the five star hotels, and they won’t give you the same sense of history and place. You’ll feel like you’re actually living in Rome. I booked a room at a five star hotel (Hotel De La Ville) and this apartment and gave my parents a choice of rooms. They of course took the apartment, and I was jealous.
The apartment is stunning and Gregorio is a great host. It’s in the same square as embassies, members’ clubs, and very upscale apartments, with private security at the gate.
