i had a great time at valter's b&b! i didn't meet valter personally, but his lovely daughter chiara made sure my stay went as smoothly as possible. she was always in a good mood and happy to answer any questions. i certainly enjoyed the conversations we had whenever we bumped into each other! the room itself is pretty large and comes with a comfortable bed, while the private bathroom is separate and rather small). the location is hard to beat if you'd like to explore the vatican and its surrounding sights (such as castel sant'angelo which is fairly close, too), there are numerous buses less than a minute away that take you right into the center. also, there are many restaurants in this area, of which "la vittoria" (right next door) really stood out with its excellent, yet affordable food. in short, i can only recommend staying at this wonderful b&b!
