I did not stayed at Julia's Domus on my own, I booked it for my parents. All in all they had a fantastic stay! First of all, communication with Tatiana, her family and all co-workers was very good and helpful - before, during and after the stay! My Parents received lots of tips and suggestions what to do!
The apartment is located in a gorgeous neighborhood with lots of cafés, restaurants and little shops. Moreover it's definitively not too far away from all the main spots. But, the area around the apt is not too touristic and thus provides an insight in the "real life" of Rome. My parents felt safe all the time and would totally recommend the stay. Especially when you plan to visit Rome for a longer time!
