It is generally recognised that Rome can be very noisy, day or night. So, if you want absolute quiet, then Beatrice's flat is the place for you. You would be on the 6th floor, in a very compact flat well away from any unwanted noise. Moreover, Testaccio is a vibrant quarter of Rome, with great food, reataurants, market and kind people. It is safe. Transport is plentiful and easy reach of the centro storico and main transport hubs. All in all, I had 11 days at the flat and enjoyed each and every day of my time there. I would certainly stay at Beatrice's flat the next time I'm in Rome.
