The location is great. Market right across the street to buy fresh produce every day. There is a small grocery shop a few doors up the street too. Vatican Museums are a short walk away. Two metro and numerous bus stops are close as well. A lift will help with getting bags to the upper floor. The apartment was very clean, tidy and quiet. Although we did not meet the host in person, she was always very prompt with the responses in our communication to make our stay pleasant.
WiFi in the apartment has a fixed amount of data available, so it might not work for everyone all the time. There is a bit of a smell in the bathroom, but it can be managed with ventilation.
