Rosa is the sweetest Airbnb host I've ever stayed with. She was very accommodating at check-in and even provided me with tips, some water, and a banana to start off my day before going to St. Peter's. The room was perfectly comfortable and larger than what you would find in most of Rome. Well air-conditioned, with a tiny fridge, and clean private bathroom. It's also a 2 minute walk from Termini Station which is super convenient.
