We had a great stay at Diletta's. The apartment is very cozy and homey-feeling. Excellent kitchen and nice living/dining hangout area for our family of six (ages 17-82). It is on the 4th floor (5th as Americans count) but there is a small lift that worked great. The neighborhood is charming. Very near several major tourist spots but off the Main Street and the windows are new, so it's quiet at night. There are actually some very nice restaurants, not just tourist ripoffs, steps away, including excellent gelato. There is also a nearby supermarket. We would definitely recommend staying here if you want to be in the center of Rome.
