My wife and I stayed at Maria Cristina's flat from Friday to Sunday on the weekend of June 6th. Her flat was easy to find with the directions she gave us. We took the fast train from Milan to Roma Termini and then the subway to Ottaviano. From there, it was a 7-10 minute walk where she kindly met us outside her flat close to 10:30PM. She walked us in, showed us how things worked, we scheduled a check-out time and then she gave us the keys. Very easy process!!! If one of your goals is to explore the wonders of Vatican City, then the location of her flat is EXCELLENT!! Just a short walk and you can be at St. Peter's Square or the Vatican Museum which was very convenient. Or, if you want to go to and from Rome, the subways run until 1:30AM. I'll also add that it was hot the weekend we stayed, but the air conditioning in her flat kept us nice and cool. The flat was clean and there were full size bunk beds which were comfortable. She provided towels and left some snacks for us when we arrived. I would come back again or recommend this to a friend.
