There are a few hills involved, but the walk is worth it. Located just a skip away from Vatican City, this location offers easy access to sites on both sides of the Tiber. Taxi and Uber drivers have a little bit of difficulty finding the building, but if you tell them it's just up the hill from Stazzione San Pietro, they'll get there. The hosts are wonderful, offering many welcoming touches. We were met with a welcome bottle of wine to celebrate our first visit to Rome, and our hostess spent some time with us, going over a hand-annotated map of the city, explaining the easiest ways to get from the apartment to all of Rome's sites and offering personal recommendations for everything from pizza to gelato. The apartment itself was adorable, and the views of St. Peter's from our terrazza were fantastic. We would stay here again in a heartbeat.
