We felt very welcome and comfortable in Claudia and Cristina's apartment. The proximity to Vatican City and other siights was a huge benefit. We rarely needed to use public transport, although there was a train station right next to the apartment buidling. The apartment was perfectly clean and tidy with very comfortable beds. Claudia and Cristina were extremely friendly and welcoming and exceeded our expectations in the assistance they provided us. There are great restaurants, a bakery, pharmacy, and supermarket in the immediate area, which made staying there highly convenient. I strongly recommend their place, especially if your visit to the Vatican is a top priority.
