We loved our stay in Elisabetta's apartment. The apartment itself is spacious, beautiful, and well-equipped with everything you might need. The definite highlight was the beautiful terrace, where we were able to have dinner or a drink after a long day of site-seeing. It's located close to Vatican City and right beside a train station with a line that runs through all the major sites in Rome (though we basically walked everywhere, which was also very doable). Elisabetta was also a wonderful host--she was very flexible about our check-in and check-out, and gave us a number of tips about the city (including some cool architectural highlights). Since people have mentioned the heat, I will say that we were in Rome for a few extremely hot days (35-38 degrees celsius, and humid) and a few cooler ones. There's no AC, but the apartment has huge windows and great shutters, and we found it quite comfortable even on the hottest days. We'd definitely recommend staying at Elisabetta's place!
