We had a great time with Arianna! Arianna and her husband are very warm-hearted and helpful people, who made us feel very comfortable during our trip to Rome :)
The room was clean and very cozy, just like on the pictures! She also served us a nice breakfast with cappuccino and croissants.
The location of the B&B is also very good: it's just 5 minutes away from the next Metro station and 2 minutes away from the train station Ostiense (30 mins to the airport).
All in all we had a great time :)
