This experience was great, my brother, friend, and I loved every second of our time spent at Stefano's. The space was clean, well-kept, and new, with interiors being recently finished while the outside is just as gorgeous. (A courtyard and trellis are the centerpieces here.) Stefano himself was there to greet us, and was kind, helpful, and always a short message away if anything was needed. (It wasn't - every necessity was already amply provided for - but he was prompt in responses at the beginning and end of the stay.) San Peter's Keys is also just a short walk from the Vatican (15 mins), and 2 mins from the local subway, which made it convenient for sight-seeing and travel. I cannot recommend it enough, and hope to be in touch with Stefano again come the next time I visit the Eternal City.
