Our stay at Luca and Fabio was great. The location was excellent; 5 minutes walking from a train and a metro station (and 20 minutes to the colosseo if you are feeling a bit energetic), and within a quiet neighborhood so you will avoid the hassle of the touristic places and have good food around at reasonable prices. We only met Luca during our stay and he was such a great guy and was very welcoming and gave us very useful tips on places to visit and dine. The place isn't spacious but it's more than what you need for your stay as you will only be spending nights there sleeping, and right around the corner is Gelateria La Romana which offers THE BEST ice cream in Rome and probably in Europe.
Many thanks Luca for your hospitality, our stay was "Perfecto"....
