Maria Teresa's apartment is in a great location for visiting the Vatican! It's a nice quieter neighborhood just a short walk away from the Vatican Museums and St. Peter's Basilica. There is also a metro stop to take you to many beautiful sites in Rome and the central train station.
The apartment is nice and modern with enough space for my family's stay. Also, Mary Teresa was extremely helpful with her offer to assist with arranging tours and transportation! I would recommend staying here for any visit to Rome.
