I stayed at Frederica's B&B for 3 nights from 23rd till 26th September 2016, a total group of 5 adults and 2 children. I would definitely rate it 5 stars. Frederica was extremely helpful and friendly and the apartment was immaculate. We all loved the hot drinks machine! Fantastic position close to the Vatican and Metro Station. I will be recommending all my family and friends to stay at this fantastic apartment.
