Our stay at Giovanna's house was perfect. The apartment is very clean and very well furnished. When we arrived, Giovanna and her husband greeted us with a bottle of Prosecco, a basket of fresh fruits and candies. She gave us a map of the city and explained what was possible to do in Rome. The location is also perfect. 10 min walk to the Vatican and if you enjoy walking you are quite near everything as Rome is not a big city. There is just a small problem, the neighbors are very noisy. You will probably be awaken quite early (5 am) during week days but no problem to sleep in on weekend. I strongly recommend Giovanna's house.
