Very nice location and easily accessible to most of the monuments in Rome!
But, we stayed in the room during November and it was very cold and not well insulated. The heating unit was loud and made rattling noises all night. And the street is very loud.
Also, breakfast was a roll and a brownie for 3 days. I wouldn’t consider this a “traditional” B&B. But fine for just a place to sleep while you visit Rome.
