The location of this guest house is perfect as it's in the center of Rome, near Saint Peter's square and close to the metro station Ottaviano.
Our room was at the beginning of the corridor so heard some noises at night but overall was quite spacious.
The negative thing is that they don't change towels for a two-night stay (unless you pay an extra surcharge), so we had to reuse the same one of the previous day. To be honest it is the first time I encounter this.
Breakfast is not included, but for the rest everything went pretty well.
