Patrizia's bnb was my first booking in a series throughout Italy, and I can honestly say it was my favorite.
Everything is exactly as advertised. A small, clean, comfortable boarding with a well stocked kitchenette. The neighborhood was reasonably quiet, yet just a quick cab ride from the Vatican area.
The only thing to note is that the shower is a little small (but the best of my trip so far). This is not just Patrizia's place, but appeared to be Italian showers in general.
What wasn't advertised was Patrizia's hospitality. She was understanding of my late check in time, arranged for a friend to let me in, and even got me connected to the wifi over the phone while she was out!
If I'm ever in Rome again I'll be staying with Patrizia!
