Diego's apartment is located in the center of the 'real' Roma! Testaccio is a thriving neighborhood, filled with authentically Roman restaurants and a bustling daily marketplace far removed from tourist areas, while still offering easy access to all of the main architectural sites of interest in Rome.
The apartment itself if charming - - newly renovated and filled with lovely designer touches. It is obvious that the apartment is designed to make those who visit it feel as though they have entered a 'home of their own' while staying in Rome.
I highly recommend that you try to book Diego's apartment when visiting Rome. You'll find the apartment and the surrounding neighborhood the perfect spot from which to enjoy all that Rome has to offer!
