We had a great stay at Emanuela & Fabio's apartment in Rome. It was perfectly situated in the middle of all of the major sites and was very well supplied with a number of great amenities, even slippers, and with plenty of breakfast supplies. As someone else mentioned, the foldout sofa is in a separate room with a door so there were no issues with privacy.
One of the best things about our stay was the awesome hosts. They let us know about events happening in the local area during our stay and their restaurant recommendations. When our early-morning car to the airport was a little late, Fabio was even available to help contact the driver and confirm his location. We really appreciate Fabio's responsiveness and support.
I highly recommend this apartment to anyone looking for a great place to stay in Rome.
