Tiziana's place is clean, walking distance from all the major sites, easy to find, and she always leaves the place LOADED with goodies. I have stayed there twice. I love it because I'm a low-budget backpacker. Tiziana stocks the refrigerator with milk, cold cuts, water bottles, and some other treats, and she leaves nutella, cookies, bread, and croissants on the dining table.
I would highly recommend anyone to stay here. I will always stay here if it's available when I come to Rome!
