Very convenient location, basically close to everything you will need if you are visiting for museums, restaurants, etc. We walked so much in Rome and I believe it was possible because of this wonderful location. Chiara is a sweetheart and she made herself available for any questions, as well as gave us maps and directions that we needed.
The room was very clean, a classic room close to St Peters square. Make no mistake, that window at the picture overlooks only a parking lot. But the location is indeed close to St Peter's.
Chiara gave us breakfast tickets to eat at the bar downstairs and the owner of that place was just lovely. You'll get a croissant, coffee or capuccino, and juice. If you want something else I believe you'll need to pay for additional items, but the available food was enough for a snack early morning!
The building is quiet, so you'll be sure to have a restful night of sleep. The room is equipped with air conditioning for those who like to sleep with it. Air conditioning machine is quiet.
Bathroom is very small, European style. Shower works perfectly, everything was very clean. Make sure you understand how to use the toilet, maybe ask Chiara. We ran into some trouble trying to flush but not enough water was going down the toilet, so I believe there might be some way to make more water available there. Ask Chiara to avoid confusion.
Chiara speaks fluent English and she made our experience very special. We had a great time and would definitely consider staying at this B&B when coming back to Rome.
