Our family of four including 2 teenagers were warmly welcomed very late at night by Bruno. The super friendly doctor speaks English very well and gave us a thorough tour of the apartment and of the neighborhood.
The apartment is ideally situated - we easily (even with my bad knees) walked to the Coliseum/Forum area, to Trevi Fountain (obviously), to the Pantheon and to the Spanish Steps. It is a stone's throw from the Triton Fountain sculpture by Bernini in Barberini Square. And a second stones throw to the Capuchin Crypt (artistically displayed monk bones) in the church of Santa Maria della Concezione dei Cappuccini. It took us a total of 20 minutes from the apartment to reach the entrance of the Vatican Museums via the nearby subway stop. Yes, the kitchen facilities are small...but who cares when just steps from the entrance to the apartment are a deli and a superb cafe for coffee/panini/pastries and around the block there is a grocery store and many very good restaurants. Nearby there is also a pedestrian-only shopping street.
The apartment is VERY quiet - no noise from adjacent interior. We chose to keep the windows open and even over the weekend the nearby vibrant nightlife does not venture down this narrow street as there are no bars along it. It also felt extremely safe - we did not worry about leaving our valuables out and about in the locked apartment. Do not expect a spacious bathroom... but it is fine. The apartment feels homey with books and artwork and it was very clean with generous supplies for whatever you need. Bravo, Bruno !
