If you don't mind to share the bathroom with another guest and the host, Ermanno's is the perfect location to visit the city. Only a few hundred meters from the Campo dei Fiori! All places of interest easy to reach. Ermanno is a gently helpful host who provided us with valuable information. We stayed in the spacious Pellegrino room .
A little bit noisy at night because of the bar in the street below.
Altogether recommendable.
