When arriving on a Sunday early afternoon, I was welcomed by Evelina and she explained me in detail the apartment and the functioning of the all the machines and the modem for internet. I felt immediately at home in the apartment and in the neighbourhood. This was the case for all three weeks there. Everything functioned well in the apartment, including and very importantly the heating in the evenings and in the mornings. The few SMS to Evelina, on practical issue, were immediately answered. I appreciated that very much. The neighbourhood is fine, within 1 minute one can purchase whatever is needed in the household, for the kitchen and there is one small and very nice restaurant quite around the corner. The location is perfect: The Vatican is within 10 minutes walk, the historic center equally and Trastevere is anyway next door, with its many restaurants and bars and else. I had never any problems with regard to security, even in the evenings. The neighbourhood is safe and after a while you know the people in the street.
To sum up, I can only recommend this apartment, without any hesitation, from all points of view.
