I spent several nights at Marcos place and found it amazing. The location was perfect. It is close to sights, trattorias, and shopping, yet tucked away where you it is totally peaceful. the wifi was good and the water-pressure was very good. It is also very easy to get to, and find if you got lost. If I return to Rome, I will stay in this exact area, and hopefully Marcos place.
Marco was very helpful when I had questions and had a list of some places to eat that he recommended. The place Casa Coppelle on his list was fantastic.
