Andrea's place is great. I stayed there with my husband and two teenage boys (13 and 16) and the place was very comfortable and clean.
The place has a great location, just a short 10 minute walk to Vatican City and 30 walk to Trastevere. There is also a train station next door that will take you to Termini Central Station.
Andrea was also very good with communication and suggestions. We had dinner at one of the restaurants he recommended in Trastevere, Osteria Der Belli. The food was amazing and the staff was great! They helped with awesome recommendations and made us feel like locals!
We definitely recommend Andrea's place!
