Barbara's place was meticulously clean and looks just like the pictures. The beds were very comfortable and our family of 6 had plenty of room. The patio was a delightful place to relax. The kitchen was extremely well stocked. It was just a block from the metro stop and only a 5 minute walk to the vatican. Lots of fun shops and restaurants right on the street (but see the note of caution below, which has nothing to do with Barbara's apartment which is a true gem). We thoroughly enjoyed our stay here and would highly recommend it to anyone. We plan to return to Rome in two years and hope to stay here again.
(One note of caution, don't patronize the restaurant below the apartment - Isola Della Pizza. They will seem friendly but then give you food you didn't order, expensive bottles of wine you don't order, present an outrageous bill -ours was over $200 - and ask for a tip. Beware!)
