The Vatican Corner apartment was exactly what we were hoping for. Sunny, welcoming and very comfortable. It was within a 15 minute walk to St. Peter's Square and the metro, and there were several stores and restaurants in our immediate neighborhood.
Our host, Patrizia, was very communicative and helpful from the time we booked the apartment months in advance to the second we arrived. She was waiting for us with keys and a tour of the place, even after our flight and transfer were a couple hours late. She even checked in after a couple of days to make sure we were comfortable and getting around easily. Her apartment matched her personality - classy and delightful.
We loved out time there and felt very much "at home". Our only crit is that the 6 days was not simply enough! I would recommend this place to anyone.
