Ai 2 Papi is 3 blocks behind the Vatican. It's about a 30 minute walk around the wall to St. Peter's Square. The bus is 2 blocks away and gets you there in minutes. Our room was clean and airy with a small fridge, fluffy towels, and soft sheets. The breakfast room is available during the day for coffee and tea, and there's a lovely small garden spot in the back for relaxing. Angelina provides cold meat and cheese, cereal, toast and jam, juice, tea, coffee, and a selection of fresh pastries for breakfast. She is very helpful answering questions, and has a map with the bus and train routes on the wall, as well as guide books in a variety of languages. One enters through a locked gate into the courtyard, then into a locked building into a locked apartment. Very safe and secure. Let her know when to expect you, as she doesn't stay on the premises. Ring the buzzer on the outer gate wall to let her know you're there. We'll stay there again the next time we're in Rome.
