A fun place to stay... right near the Vatican, but... If you don't speak Italian, I suggest you choose another hotel/B&B. Although the staff/(owner??) is VERY personable, she speaks only Italian and you must call them to tell them when you will arrive. Also, you must go to one location to check in, and another location (several blocks and streets away -- it's not "across the street" as the directions say, and they did not provide a map. Trying to get directions from someone speaking another language who doesn't understand you is almost impossible.) It took us an hour and a half and three trips between the two locations to get checked in.
We booked for several nights. After the first night, there was no hot water in either of the shared, hall bathrooms. Since we had so much trouble communicating, we just did sponge baths instead of showering.
If you speak Italian, then go for it! You'll really love the location of either the main B&B or the "annex". Both are close to the Vatican area. Breakfast of croissants, corn flakes and milk, and sometimes bananas is included.
